Well, every unnecessary or very rarely used global tree means typically
another GC root or global variable that needs to be handled on every garbage
collection. So the question is if it is worth it.
As for sharing the code, I've actually started writing such an inline
function, but then realized that every of the spots that use such a
technique does something slightly different.
