I think if we are going to emphasise the difference, a decorator does
not go far enough. To use a decorator, this *must* be valid syntax::
def gen():
try:
yield
finally:
print 'Done!'
However, that generator cannot be properly used in a for-loop. So it's
only realistically valid with the decorator, and used in a block
statement (resource suite ;)
My feeling is that the above should be a SyntaxError, as it currently
is, and that a new keyword is needed which explicitly allows the above,
and creates an object conforming to the resource protocal (as I called
it).
