enum Enum { en1, en2 }

void main()

It probably has something to do with name-mangling.

I think so not a bug,
it's work:

with (Enum) {
    if(matchAny(en, en1, en2))
        "test-ok".writeln;
}

It's still a bug, if you use braces the bug isn't reproduced:

OK:
    with (Enum)
    {
        if (matchAny(en, en1, en2))
        {
        }
    }

Linker error:
    with (Enum)
        if (matchAny(en, en1, en2))
        {
        }

Okay, samples below can be read at compile-time error messages:

Sample-1:
void main()
{
    Enum en;

    with (Enum)  // <-- ERROR: found '}' instead of statement

}

Sample-2:
void main()
{
    Enum en;

    with (Enum); // <-- ERROR: use '{ }' for an empty statement, not a ';'

}

Well, this code is doing what you want! Yes, it's a linker bug...

void main()
{
    Enum en;

    with (Enum) // <-- NO ERROR!
    if(true) en1.writeln;
}

Surprised...:)

OK:

import std.algorithm;
enum Foo { A, B, C }
int main() {
    with (Foo) {
        return canFind([A, B, C], C);
    }
}



Linking error:

import std.algorithm;
enum Foo { A, B, C }
int main() {
    with (Foo)
        return canFind([A, B, C], C);
}
