Some other ideas: $cb = (callable) $obj->bar;

Ah, but (callable) that won't work for global functions, since (callable) is a cast, and

(callable) is not usable as a cast (at least in 5.4.7): $a = (callable)'str'; // Parse error: syntax error, unexpected 'callable' (T_CALLABLE) This could work, and it makes sense to me at least. Yes, the problem is that it would add a special syntax case, where (cast)identifier, in this case, uses a function name, not an expression. This is bad.
