That approach has good qualities like allowing systematic comparison
with the original.

Looks like "#define iscollectable(o) (ttype(o) >= LUA_TSTRING)".

I sympathize with the difficult to understand part.  Trying to
determine what a piece of code does seems to involve a tree-like
search through inter-dependent code, broadening the search and making
inferences where comments and naming are sparse.  A code browser
obviously helps here.  This has been mentioned in the past [1-2].
