OK, I was exaggerating to make a point.
I wouldn't make assembler my starting point unless there was a really good
reason to do so. My latest efforts have mandated an assembler fragment
because I couldn't initialise the stack pointer and MMU any other way (not
sensibly anyway), but such is an example of where I use that medium - only
when there's no sensible alternative.
