No, it won't.  Python draws a very strong distinction between expressions
and statements.  This line has been blurred somewhat with the advent of
 comprehensions and the if-else expression, but it would still require more
benefit than three characters in a keyword saving to allow def use in both
statements and expressions.

The following, for example, does not look pythonic at all:

*def* transform(*seq*, *func*=*def*(*x*):*x*):
      ...

(Note that I attempted to emulate syntax highlighting to make my point.)
