This would be a cornerstone improvement, in my opinion.

I didn't know. FeatPost uses some equations but pre-solves many others.

FeatPost uses only `defs' and `vardefs'. Macros need to be implemented
to allow FeatPost macros to have a chance of being reimplemented in 3DLDF.

The manual is another cornerstone...
