Speaking for myself, I almost never put any logic at the top level in
anything other than tiny throwaway scripts. Top level is for
importing, and defining functions, classes, and constants, and that's
Even when doing things like preprocessing I'll define a function and
call it rather than putting the logic at top-level. Sometimes I'll
throw in an if-test at top level (for the kind of stuff I might choose
an #if preprocessor statement in C for) but mostly I just put that in
