Hi,
Is there a chance that we can add an operator() to the
reference wrapper? In particular, I would like to be able
to use it as a nullary functor. This would obviously be very
useful and should not disrupt the current code. In particular,
consider Spirit's conditional parsers (as once asked by
Beman).
if_p(c)
[
parse_this
]
The condition is expected to be a functor that returns
a boolean condition. I was hoping that I can use the
ref(b) as a functor such that I can write:
bool b;
if_p(ref(b))
[
parse_this
]
Of course I can metaprogram the condition to dispatch
appropriately when the condition is a reference_wrapper
but it wouldn't be as simple and elegant.
Thoughts? TIA.
