I’m not sure that having the temporary created 200 lines before it was used would be improved with either of these cases! ;-) Allowing the compiler to infer type seems like a big win, for all the same reasons it is for SML and other Hindley-Milner languages. Why must I manually enter stuff that the compiler should be able to determine for me? Our development environments should be capable of showing us the resulting ‘auto’ type, so I feel like requiring explicit type declarations are a step backwards. -Brent
