I can't understand why this won't work, either:
>>> aaa=4
>>> 1.aaa
  File "<stdin>", line 1
    1.aaa
        ^
SyntaxError: invalid syntax

And:
>>> 1.(aaa)
Traceback (innermost last):
  File "<stdin>", line 1, in ?
TypeError: call of non-function (type float)

:)

>>> (1,2).aaa
Traceback (innermost last):
  File "<stdin>", line 1, in ?
AttributeError: 'tuple' object has no attribute 'aaa'
>>> (1,2).(aaa)
  File "<stdin>", line 1
    (1,2).(aaa)
          ^
SyntaxError: invalid syntax

Gerrit.
