Well - indents and loops and such is just ordinary Python code. Do you 
want this code to be entered one line at a time, like an interactive 
interpreter?

If you're executing code from a multiline textblock - then it shouldn't 
be  a problem as you won't be executing code one line at a time...

In Mike Stall's article

'Evaluate' executes a single expression and returns the result.

'Execute' executes a block of code.

That article is from 2005 though.
