your call :).

Btw, if __exit__ is the only spelling then:

   var = expr

   if hasattr(var, "__enter__"):
     var.__enter__()

   try:
     suite

   finally:
     var.__exit__()

is maybe a better semantics. If someone uses some of his
legacy file-like objects etc, but forgets to define at least __exit__, he gets
a fail-fast behavior, otherwise he may have to track down data corruption 
or something
like that...
