To answer the specific question, no, there is no reason to not qualify it.
Argument-dependent lookup doesn't work with function objects (but there is a
defect report on this); it doesn't work on template-ids (but there might be
a defect report on this in the future if Gaby submits it ;-) ) and I don't
believe that it's the intent to pick up less<> versions in user namespaces.
