That may be true. OTOH, the authors of System 3 (ETH Oberon),
Oberon V4 (Linz Oberon) and A2 (formerly) - all considerably
larger systems and Original Oberon - also don’t seem to use
local procedures or locally declared types very much. And I
don’t think the authors of these systems blindly follow someone
else’s programming style.
