    G++ is notorious for producing "sub optimal" template
    code in some shape or form. However, things do "just
    work" from a consumer's POV, and correctness is what
    matters most here. Speed is a distant second, and any
    musing about that now is nothing more than premature
    optimization (thx, Herb Brooks).

    Just out of curiousity, what version of G++ were you
    testing against?
