silences "possibly useless use of :: in void context" warnings

The AS utility silence_warnings does not really silence this
one, because it is issued at parse-time. It seemed to in
some places because the constant was the only expression in
the block and therefore it was its return value, that could
potentially be used by silence_warnings are return value of
the yield call.

To bypass the warning we assign to a variable. The chosen
variable is "_" because it is special-cased in parse.c not
to issue an "assigned but unused variable" warning in turn.
