It should be.

If you're using a template mixin:

template foo(T)
{
    T bar;
    static this()
    {
        bar = something();
    }
}

mixin foo!(int);

If you're using a string mixin:

template foo(T)
{
    const char[] foo =
    T.stringof ~ ` bar;
    static this()
    {
        bar = something();
    }`;
}

mixin(foo!(int));
