Here's a hack: i know about hackish way, but it's SOOO UUUGLY... ;-) thank you anyway. > But the two leading underscores tell it: "__ctor" is an > implementation detail. It may disappear/change without notice. ah, that's ok, i'm relying on other implementation details too, one more will not make much difference. thank you people. seems that there is no "official" way to call such constructors. ok, i converted it to autodeducing one, one more argument doesn't really matter, it's hidden in another template anyway. i was just curious if i missed some nice syntax here, or we have no way to do this without resorting to hack or factory function.
