Sure I agree, although it may depend on what the function actually does
and how you name it (and the arguments). If you e.g. rewrite your example to
def subtract(from_, what=0):
return from_ - what
the changed order of arguments seems quite intuitive to me.
What I meant in the first place is that it might be "unintuitive" that
if you pass only one argument this is the one that comes last in case
you pass two arguments.
As I said, I was not sure and was too lazy to think much about it :-)
