One project that I think is related to Wikilambda's goal of developing a comprehensive repository of functions is the "Function hub"
(
https://fno.io/hub/search) that was developed during Ben de Meester's Phd as part of the Function ontology (
https://fno.io/).
I think it can be considered as part of the related work and maybe gather some inspiration from it.
