Re: [boost] [switch] Is there any interest in library switch extention?

The library should do something like:

BOOST_SWITCH( "hello world" ) { BOOST_CASE( "hello" ): BOOST_CASE( "world" ): ... break; BOOST_DEFAULT: ... };

I hardly see how this could work for a O(1) lookup (the point of the switch statement). For it to work on strings, you would need to work to provide the possibilities as compile-time strings and generate an automaton with nested switch statements. Something like that, yes, that would be very useful. I suppose the switch_ utility can be reused to simplify matters.
