Unfortunatelly, yes - my implementation is much, much nicer, but a similar 
concept is used. :(

However, I've just tried with latest Comeau compiler (maybe I shouldn't 
believe them it's 100% standard compliant), with strict compiling mode turned 
on - and mine implementation works there!

What's the problem with overloading (one imaginable would be that compiler 
finds the best possible match, while the standard (maybe; I don't have it) 
says that a first available should be used)?

Thanks and sorry if I'm boring or vastly offtopic.
