You can already drop phi, if that's all you want to do, by excluding the phi symbol from the search with the option -Nf.
Adding constants and functions was and is a conscious motivation from the very start, and I consider it in any refactoring and enhancements. In the source code you can see that I've already specified the syntax for custom constants and functions through the existing -include mechanism. For example:
--define : EulerGamma # seft-a (constant)
( -- The Euler-Mascheroni constant, 0.57721... )
# 50 digits for when RIES goes to higher precision
This isn't implemented yet but at least I thought of it.
