'=' has too srong an association with assignment for me, The first thing I
wondered was where the '=' was assigning to. Then I realized that, in the
context of decorators, it has to be the function/method that follows. So
in the following example:
=classmethod
def foo(arg1,arg2):
...
'foo' '=' a classmethod. This does broaden the meaning of '=' from just
equality of identity to belonging to a group, but that's mostly okay.
However, the next example really bugs me:
=accepts(int,int)
=returns(float)
def bar(low,high):
...
'bar' '=' in no sense an 'accepts' or a 'returns'. It doesn't seem right
to use an assignment operator for decorating.
Keeping Tim's comments about ':' in mind, my personal favorite is '|'.
