Combine enable_if and concept check

[Johan Torp]

Is there any way to combine boost::enable_if and the concept check library? For instance to disable a function overload for template parameters which doesn't model some STL concept.

Best Regards, Johan Torp

Nope.  Those concepts perform checks that cause hard compile-time
errors.  Once they've failed, it's too late to recover... and not all
concept check failures can be converted to non-error true/false results
in C++03.
