Are you familiar with C? I'm trying to extend an existing program by adding 1 function via an existing extension point -- I am totally baffled and completely stuck, though.

I am trying to extend fe (https://github.com/rxi/fe) by ways of its existing C api (https://github.com/rxi/fe/blob/master/doc/capi.md#creating-a-cfunc)

The function I'm trying to add is actually already baked into the program, just not exposed through the repl. I'd like to add the ability to load a .fe file by calling something like (load "file.fe").
