This may already have been suggested but I really don't want to search through 200+ pages.
It would be really cool if axe supported compiling axe code into axioms. When selecting which shell you want to compile for you would simply just need to select axiom. A #AxiomSub(name, token-that-is-being-replaced, number-of-args) token could be added so that different functions could be added. This would make so many more axioms show up for axe and also some libs like TheMachine002's glib and many others. There is also the added bonus that any time you want to use a lib that is written in axe you don't have to wait as long when compiling the code because it is already precompiled.
By compiling in axioms in axe it means that code that is made for an old version of axe will still work (assuming the required structure of an axiom doesn't change). I don't know how difficult it would be to implement so maybe it is not possible. (Runner?)
If we had this it may be very helpful to those who are new to axe because could just use tilemapping lib for example instead of having to learn a lot all at once. Any thoughts anyone?
