I get these errors

from compiling the following code

struct A
{
    void b()
    {
        size_t y;
        mixin(c!("y"));
    }

    template c(string x)

        const char[] c = "

I can only find bug 276 (http://d.puremagic.com/issues/show_bug.cgi?id=276) which seems related but looks like it was fixed.

I am using dmd 2.062 on Ubuntu Linux 12.10.

Is this a bug? Or maybe bad code?

Thanks

It's bad code. What were you hoping for the code to do?
