Hi!

I'm having trouble with named typed enums.
This works (unnamed):

enum : string
{
a = "a",
b = "b"
}

int main(string[] argv)
{
writeln(a);
return 0;
}


But this does not:

enum X : string
{
a = "a", // Error: Integer constan

t expression expected

// instead of "a"
b = "b" // Error: Integer constant expression expected
// instead of "b"
}

int main(string[] argv)
{
writeln(X.a);
return 0;
}


What did I miss?

I don't know. It works for me.

import std.stdio;

enum X : string{
    a = "a",
    b = "b",
}


int main(string[] argv) {
    writeln(X.a);
    return 0;
}

compiles, runs and prints "a" as expected.

Are you using the latest version of the compiler? (DMD v2.056)
