In my case it was Marxism (:-))

I think there was a reason behind. Our major was applied mathematics.
C was hardly suitable for that (no true arrays, no overflow checks
etc). {}-brackets alone were a big problem that time. I saw an Algol
compiler that required all keywords be put in ''-quotes, like 'BEGIN'.
Presumably, because the machine had only capitals (:-))

Lucky were you. My C compiler took about 5-10 min for hello-world (5-6
passes or so) on a PDP-11, so I switched back to MACRO-11.
