OK.  Is "multiplication" a slight enough variation of "multiplies?"  If not, what variation would you consider slight enough?

Did you try the thought experiment I suggested in my last post?

What about all of the "is_" prefixed traits and other names in Boost.TypeTraits with prefixes like "add_" and "remove_," and those without a prefix?  There's clear precedent for different prefixes for different purposes within the library.  Remember that "has_" implies ownership or inherent characteristic which doesn't apply to a namespace scope operator.
