Joel de Guzman: ...
template<class F> void g( F f ) { h( bind( f, _2, _1 ) ); }
int main() { g( _1 < _2 ); // fail g( unlambda( _1 < _2 ) ); // works }
A top-level lambda[] that does let()[] will not work for this case.
Yep, I'm keeping the behavior of protect, not unlambda.
What is the current Phoenix way to make the above work?
As I mentioned in my other post. val(_1 < _2) can probably be the unlambda behavior.
This doesn't feel right to me. val(x)(...) returns x. val(_1 < _2)( 1, 2 ) ought to return _1 < _2. unlambda( _1 < _2 )( 1, 2 ) returns true.
