I recently stumbled across the proposal of removing `callable` in Python
3000 (http://python.org/peps/pep-3000.html) catching an exception
instead, maybe something like this:
--- snip ---
[mize at lxmize mize]$ python2.3
Python 2.3.3 (#1, Apr 6 2004, 01:47:39)
[GCC 3.3.3 (SuSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> i = 5
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: 'int' object is not callable
--- snap ---
This is not an option for e.g. IDEs as some functions might actually do
something when called ;-) and I like `callable` for introspection.
Other ways would be to check for the `__call__` attribute or use several
methods of the `inspect`-Module, both of which are not better than
Insert a sig please.
