User defined types can be converted to arrays.
type Foo {
bar: string
baz: bool
}
const foo = new Foo {
bar = "bar'
baz = true
}
if foo.baz {
print(foo.bar)
}
// is equivalent to
const foo = new Array<any> [ 'bar', true ]
if foo[1] {
print(foo[0])
}
There are two ways this could be accomplished: rewriting user-type creation, access, and updates in the user's code to work on arrays, or converting the user type statements into microstatements involving arrays like this:
type Foo {
bar: string
baz: bool
}
const foo = new Foo {
bar = "bar'
baz = true
}
if foo.baz {
print(foo.bar)
}
becomes
const foo = newarr()
pusharr(foo, 'bar')
pusharr(foo, true)
const cond = copyfrom(foo, 1)
condfn(cond, fn {
const out = register(foo, 0)
print(out)
})
The microstatement approach looks like it would be the simpler to implement as none of the translations appear to require manipulating multiple statements at the same time.
