Especially given that Python's comprehensions are taken from Haskell's 
which are taken from mathematics' set builder notation.  Also, care was 
taken to have a correspondance between comprehension syntax and nested 
for- and if- statement syntax.  Someone recently made a proposal that 
would break that correspondance and which would be 'ad hoc' and it will 
surely be rejected.
