Can we pass by value instead of by const reference?  I'm not sure WTF::bind is
smart enough to handle references correctly.

Hm AFAIK normally functors only accept const-versions of reference arguments
precisely so it can make a local copy, but I'll double-check this.

Yep the type trait at wtf/Functional.h:325 should handle this correctly; it'll
take a local copy of the struct.
