Re: Block lambda is cool, its syntax isn't

Axel Rauschmayer January 20, 2012 5:34 PM 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!). It's hard to type λ on many keyboards. ƒ is easier, but neither is backward-compatible: js> ƒ = 1 1 js> ƒ 1 js> λ = 2 2 js> λ 2 We rejected these already for these reasons. I think "use fn;" (real pragma syntax), with the low-precedence assignment-_expression_ fn (params) assign-expr production, wins. What do you think? /be
