Re: Class Keydata - similar entries from multiple sections?

[David Sugar]

Normally you would load each [] into a different keydata object.  If you
merge keydata sections into a single object instance, there is no means
to determine which instance it was loaded under.  Mostly merging is
meant to load "default" keys into a given object, and then override them
with live values.  At least that was the intended use.
