Hmm, from what you are saying, it seems like there's no elegant way to
handle run time defaults for function arguments, meaning that I should
probably write a sql-esc coalesce function to keep my code cleaner. I
take it that most people who run into this situation do this?
def coalesce(*args):
for a in args:
if a is not None:
return a
return None
def doSomething(debug=None):
debug = coalesce(debug,defaults['debug'])
# blah blah blah
