Subject: [PATCH] api-macro: replace ident hashmap with simple find

after benchmarking (again), i found that doing a simple find instead
of saving the inidices for the ident strings in a hashmap has
no real performance impact (the max list size for the properties
are max ~25 at the moment, so this should not be impacting compile
times much) but it is much simpler
