Re: [Python-ideas] Where-statement (Proposal for function expressions)

      ...
or maybe better:
while foo(x) and bar():
     where:
         foo = SOMETHING
         def bar():
             SOMETHING ELSE
     THE
     LOOP
     BODY
Another possible variant:

while foo(x) and bar()    # no colon
where:
         foo = SOMETHING
         def bar():
             SOMETHING ELSE
do:
         THE
         LOOP
         BODY

But the former has such an advantage that where-block content is
indented deeper than loop body -- what reflects that it (where-block)
creates nested scope (contrary to loop body).
