Yes, please.  I've been wanting that for years.

The counter-argument is that inhibiting all warnings for a whole statement
or a whole expression is dangerous, because it might inhibit warnings that
indicate real problems.  However, what I end up doing to work-around the
absence of __nowarn__ is inhibiting certain categories of warnings for my
whole application, simply because one header file contains an occurrence
of code which triggers such a warning and for which the warning can't
easily be supressed.
