Does either of the suggestions for debug actually "work",
stylistically? Specifically, consider the preparatory code required.
This looks awful to me:
def debug (f):
debug = False # gag, retch, puke
@debug if debug else lambda f: f
The comment may be *little* extreme, but surely that's not very
beautiful in your eyes? Isn't
debug = False
def instrument (f):
return decorate_for_debug(f) if debug else f
preferable? Caveat: I'm of the school that lambda isn't very
beautiful itself, not in Python.
