Thank goodness someone is cleaning up C++ while still maintaining a goal of high performance! Elements of the language that are there entirely due to historical reasons should be gotten rid of. Since Clay has keywords "Int64" and "Float64", "Long" and "Double" should be gotten rid of since they are basically misnomers (being shorthands for "long int" and double-precision respectively but that not being implicit in the names).
