One problem I have with the pie-decorator syntax is that it is very
typographically dense. The @ character runs in with the following
function name. If there are multiple lines of decorators, the problem is
worsened. For clarity, the decorators will have no whitespace lines
between them, creating a dense block.
After experimenting, I have found that readability is increased if there
is one space required after the @. Don't take my word for it:
Current Python 2.4a2 syntax:
@framework_stuff(lots, of, args)
class Quux(object):
@check_args(int, str)
@counted
@staticmethod
def frobnicate(foo, bar):
pass
Proposed change requiring a space:
@ framework_stuff(lots of args)
class Quux(object):
@ check_args(int, str)
@ counted
@ staticmethod
def frobnicate(foo, bar):
pass
