pythonwin framework: directly execute marked stuff?

[Robert Kiendl]

when writing pythonfuncs in a sourcefile one often wants to immediately
test little code fragments without running the complete file.

emacs-lisp trains support such style of work in a good manner.

is it somehow possible in pywin to mark a few lines and have them
directly executed interactively - thereby removing topmost indents?
doing this with copy-paste-removetabs is tedious.

or can someone give a quick-tip how to attach own code for such style of
behaviour to the pywin-editor?
