The syntax `type A[B]C` can be reduced both in Go1.17 and Go1.18 in only way - it's declaring an array type A, having B elements of type C. Because B must be a constant expression, which `float64`, unless redefined, is not, the error message produced is complete and unambiguous. Compiler error messages say what the error is, their purpose is not to explain the specification. The intended reader of the error message is supposed to understand the message in context of the language specification, i.e. in this case be aware that the code declares an array type, and expects an expression where a type `float64` was found instead. FTR: To have it explicit, it has nothing to do with type parameters, they have syntax incompatible with this given example. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
