That’s pretty significant relative to the size of the Oberon
compiler (in other languages it would be considered negligible)

In other compilers a 10% speedup would be quite noticeable (one
coffee less to grab during compilation), but not in Oberon
where compilation already is near-instantaneous.

PS: I believe this is the only place in the Oberon system where
one would see a measurable performance gain (here 10%) speedup
(correct me if I’m wrong)
