I'm 99.99% certain that it's perfectly legal to pass a temporary to a function 
that takes a const T& and that it's in the standard. I'm fairly certain that 
I've read it in at least one book (though I'd have to look it up to be sure), 
but regardless, both gcc and Visual Studio definitely allow it, so if it's non-
standard, it's still highly supported.
