Allow SourceCodeKind statements to return value about main

[DinoV]

There is an overload in the parser which does this, Parser.ParseFile(bool makeModule, bool returnValue). Passing true for returnValue causes this behavior. If you use the SourceCodeKind.AutoDetect it’ll flow true in for the returnValue and you should see the desired behavior.

Subject: [main] Allow SourceCodeKind statements to return value (#190)

IronPython, similar to CPython, has modes for how to evaluate code. Expressions will return a value, but I don't think any of the statement-oriented evaluations will return a value. However, IPython has another manner of executing code that will return the last expression, even if after a set of statements. For example, if you enter this in a cell:

x = 1

y = 2

x + y

You'll get "3" as output. The way that they do that is to parse the input, and evaluate each statement, returning the result of the last one. This is really handy when doing cell-based computation as it allows the last item to be displayed/viewed/used.

It would be nice if IronPython allowed this type of evaluation.

Thank you; that worked like a charm!

Can we close out this issue then?

From my perspective, yes. I don't know if this documented anywhere... that might be the only action item from this. Thanks!
