Technically they are part of a "namespace", since you can disambiguate them:

-----
mixin template T1()
{
    extern(C) void fizzle() { }
}

mixin template T2()
{
    extern(C) void fizzle() { }
}

mixin T1!() t1;
mixin T2!() t2;

void main()
{
    t1.fizzle();
    t2.fizzle();
}
-----

So I guess that's why they're mangled. As a workaround you can use this:

-----
mixin template T()
{
    // or just pragma(mangle, "fizzle"), but this will at least error if
    // you change the function name
    pragma(mangle, __traits(identifier, fizzle))
    extern(C) void fizzle();
}

mixin T!();

void main()
{
    fizzle();
}
