In principle I do agree with you that most developers don't care about
the underlying implementation of how parameters are passed. In my
specific case, performance is extremely critical in the project we're
working on, and knowing things like this are important to squeezing
every last bit of performance out of our code (it's faster to pass a
pointer to the record than put the whole thing on the stack).
Anyway, thanks for your insight. Sorry to bring up a discussion you've
already had a few times (as Michael said), I guess I need to Google
better next time. :)
