This is related to issue #1742.  In the code below, calling proc_!(char).fn
explicitly in the global scope works, but calling it explicitly in a template
function fails.  I would expect both to work.

    template proc_( T )
    {
        size_t fn( in T[] a, in T b )
        {
            return 0;
        }
    }

    template proc( T1, T2 )
    {
        size_t proc( T1 a, T2 b )
        {
            return proc_!(char).fn( a, b );
        }
    }

    const a = proc_!(char).fn( "abcde", 'c' );
    const b = proc( "abcde", 'c' );

    void main()
    {

    }
