Allow enums in local scopes #3217
Description
Currently the following is allowed:
enum Color { red, green, blue }
function fun(myColor) {
if (myColor == Color.red) {
console.log("awesome");
} else {
console.log("bummer");
}
}This compiles, but gives a warning:
function fun(myColor) {
enum Color { red, green, blue } // Warning "Statement expected"
if (myColor == Color.red) {
console.log("awesome");
} else {
console.log("bummer");
}
}Especially when refactoring existing JavaScript code, there are cases where an enum would be useful, but wouldn't be used outside of a single function. In those cases, I think it makes sense to allow the enum to be defined inside of the function's scope.

Presumably this could be considered along with other kinds of types we would allow in a future 'local types' feature. Edited the title appropriately.
