It is historically interesting, but does it really matter?
The important characteristic of the syntax is its convenience to humans,
and if that requires slightly more work from the compiler, then so be it.
AFAIK, most modern compilers moved to recursive descent parsers
due to similar reasons.

Present your examples then ;-)

Of course, I understand that. My examples were aimed not at direct
compatibility, but the spirit of minimalism that was the driving force
of the Modula/Oberon design.
Besides that, what useful features do you think
Object Pascal / FPC might take from Oberon?
