Live Coding with AutoHotkey.dll.
When I am coding in autohotkey, I always bind the reload command to
Listvars window and the
ListLines window are always available as a debugging aid. Now running a script in AutoHotkey.dll, you can modify variables in a running script using
ahkassign. I think with the com interface to vim, it wouldn't be hard to make changes flow into the source code. AutoHotkey.dll also allows you to load a script but not execute it. Then you can access the abstract syntax tree of the script using the dll's introspective capabilities.
