Yeah.
$ alias rm="rm -i"
and you get the annoying "confirm all deletes" behaviour.

Right. There are SO many special cases here that rm cannot possibly
catch them all:
# cd / ; rm -rf foo/ *

This space is a typo.

Many others as well.
"Windows' job is to prevent you from shooting yourself in the foot. With
UNIX, the idea is to make damn sure that there is a hole in your foot with
the greatest possible efficiency." (Paraphrased)
I've typed "rm -rf *" in the wrong place. ONCE. I learned Unix-fu from that
experience. Now, if I type "rm <anything>", I wake up.
