Thanks Derek, sure it is nice solution for this case. I use this exact 
technique for xml parsing rules definition. And it would be even nicer 
to have static initialization of static associative arrays... Hope 
Walter get tired of regular requests for it and will implement it 
eventually =)

I wonder if static associative arrays lookups works as fast as switch 
statement?

But original idea was to mixin some cases to switch in a sophisticated 
(possibly library) function. Sure my example were simple, but thats for 
not overflood message with example code.
