Sorry for a plug, but MS VC++ 6.0 (!)* allowed for Pause->Edit Code->
Quick compile->Resume Execution kind of workflow...

Yes, in Debug/Pause mode, you COULD write a {code block} and then go
Debug->Apply and Continue (or something like that) and voila,
you could totally change code paths ... 
(Not that I know much about internals/constraints of this, to be honest, 
but of all, i found that a very cool feature)

Is there a way to add THAT to FPC/Lazarus/GDB world ? 

(especially simulation/image/OpenGL Artists would be grateful :) )
