It's the other way around...

Unless there's a direct semantic meaning of the numbers, things like
that (ie. "methods") should be represented as strings.

Else we fall back to the realm of "magic numbers" which sucks and causes
all sort of pains when several new methods get added by different
people, etc...

The tree is meant to be generally human readable and we should stick to
that. The tiny memory usage is irrelevant on any modern setup.
