Yeah, this will be MUCH faster for large switches,
because hashing is typically very fast, and hashtable
lookup is more or less constant time.

What would be 'generally' useful is a genuine switch 
statement -- a sort of unrolled dictionary whose values
are pieces of code. Syntax?

	switch x:
	case 1: ..
	case 2: ...
	default: ...

like C, except that each handler has an implicit
break at the end of the handler suite (no fall through,
like in C).

Comments?
