alex23 disagrees. alex23 finds the lambda extremely convenient for 
things like sort, filter etc where alex23 wants to provide a function.

alex23 finds this to be very readable:

     odds_list = filter(lambda x: bool(x % 2), some_list)

By comparison, alex23 finds this to be more cumbersome for little gain:

     def odds_only(x):
         return bool(x % 2)
     odds_list = filter(odds_only, some_list)

alex23 finds most examples for multiline anonymous functions to be far 
more difficult to parse than the both restricted lambda form and the 
separate function approach:

     odds_list = filter((def(x):
         return bool(x % 2)), some_list)

alex23 isn't even sure if that's the correct format for your proposed 
syntax, or whether `, some_list)` has to appear on a separate line, or 
even if the () around the anonymous function is even necessary (alex23 
assumed it was from your description of the closing parenthesis popping 
the "space-sensitivity-stack").
