simplify words down to just core words. others to be loaded as needed.

issue is: while using def it would be great to have some (non-point-free) access to locally named stack items (you may know of them as variable, but lets consider them constants, because we should not need them to mutate)...

Make examples with explanations should replace the testes on the Try Pounce page.

Word type declarations
parse or link time checking
implied types (duck typing? or fully resolved)

try Malpaux/fbp-types

canvas module: get the target canvas DOM element id from the stack... canvas should not be hard-coded. Update examples

The string '+' is interpreted as the word + and not as a string.

make a Joy like ifte word that notably expects a quotation for the conditional

(e.g.
[m:number x:number b:number]
[m x * b +] [my-linear-function]
define-with-named-args
)
or how to implement the quadratic formula.

since the encapsulation of the pounce library, isNumber was previously available, but is now private (in a JS closure)
io_canvas_basic.js:56 Uncaught ReferenceError: isNumber is not defined

example: "12.6what is this, but a string" incorrectly puts 12.6 (numeric) on the stack.

warn user before leaving the page and/or save state in local/session storage

The parser should add an empty string to the pl when it encounters special syntax ' ', '[' '{' etv.

need a pre-parser scan to 'recall' the definition of a (user defined) word and place the definition in the input text editor for user revision.

Show the definition of words and facilitate recursive expansion..definition editing and deletion of words (remove from run time -- only for use in modules not part of the the run time execution)) and put in IDE.

list_module import
[6][7 +]
pop [swap] dip

is wrong

checking for excessive stack size or run cycles will help the IDE protect users form simple errors

Runtime will need to handle either a wordStack (current) with a object wrapper around word dictionaries --OR-- change to a dictionary of dictionaries format (e.g. {nameSpace:{word1:{}}}).

runtime.js needs to support an IDE that is debugging a running program and wants to know the current imported dictionaries (currently loaded) (i.e. runtime needs to expose wordStack or wordNameSpaces and the findWord function)

(self deprecating humor: currently pounce pollutes the global space like a cat w/out a cat box -- seriously dude that smells bad)

only run def or define or un-def with a submit button or the Enter key to confirm the request.

OR only run def and define from the ui (not the language input box) for example maybe there should be a whole word dictionary UI that helps you find, use and define your words.

input tag (type="text") should respond to the placement of the cursor
FYI If possible add this feature in a way that allows a transition to a future change from the input tag to a graphical component that displays and allows edits to Pounce words, painted on a canvas or svg tag.

When a word starts with a number, the parser breaks the word into two words
(e.g. the word 4square is incorrectly parsed as [4, 'square'], but instead it should be parsed as ['4square'])

make a ctx amd draw a line and clear the canvas

just plain
#
on its own line with nothing after it causes a parse error
SyntaxError: Line 1: expected [^\n]

a new type of define 'local-def' that only works within the scope of a word (i.e. local-def produces 'helper' words that are not available globally.

time to bootstrap and dogfood the parser

A 'C' or 'C++' Interpreter is needed to support IoT and embedded applications. Possibly use nim to generate C.

When a word declares that it expects the stack to have a number of items of a certain type and possibly additional validation of the value, it should check the stack (when feature-flagged ON).
If it does not find what it was told to 'expect' it should throw errors (or fall through to a synonym word).
