Forms such as:
[ f(23) for f in stuff if callable(f) ]
have been in Python for years now, and you could indeed
say "the very first thing you see" (the call f(23)) is "getting
short-circuited" by an if-guard at the very end. If ternaries
had syntax similar to list comprehensions (but with
mandatory if and else clauses and no for clause, instead
of a mandatory for clause and optional further clauses),
as in:
[ f(23) if callable(f) else None ]
then people's familiarity with LCs (very popular constructs)
might help alleviate the "unexpectedness". (Pity about the
brackets where no lists nor indexing nor slicing are involved ).
