Opps.. of course I'll change it :)

Will be fixed.

I think there is no one.. just hadn't thought enough when wrote the code.
I'll fix it.

Good point. I overlooked this refactoring...

I don't think so. From the section 14.6 [temp.res] of the standard ( para 5,
p. 258):

... 'The keyword typename shall only be applied to qualified names, but
those names need not be dependent.'..

'T&' and 'const T' are certainly not a 'qualified names' :)
