Hi,
Is there a way to detect at compile time that a certain type is a
Boost.Spirit.Qi parser? That includes template expressions and grammars.
Basically, I want to detect if qi::parse(b, e, expr) would be a sensible thing
to do.
I tried this:
boost::is_same<
typename proto::domain_of< ExpressionT >::type,
spirit::qi::domain
>
But domain_of returns default_domain for Boost.Spirit.Qi template expressions.
