This is correct, but it is using the last bit we have available. Any other bits
we need will mean we're making this object significantly larger which is going
to have some serious performance overhead concerns given how many functions
appear in a TU, or we're reducing the number of parameters we support in a
function declaration (cutting that value in half, at least).
Are we sure we want to use this bit for these purposes?
