How much does the fact that a symbol *could* be used (in theory) matter in practice? Most regexes I see for valid identifiers are still of the ^[a-zA-Z_$][0-9a-zA-Z_$]*$ variety.

I’d expect λ to be in use in Greece, but how about ƒ (which has been mentioned many times)? It seems very appropriate and is even easy to type on a Mac (easier than square brackets on a German keyboard!).
