I agree that there are some inconsistencies in the naming of functions and parameters like destructive/non-destructive variants and predicates among other things. Also strange names like car and cdr (which on the other hand allow for cadr et al.). However, even though they can be confusing, I wouldn’t put the equality functions in the same bag.
