There's another good thing about Erlang assignment: it's not really
assignment.  Which is good, because assignment is a pretty weird
concept.  We just forgot.

Years ago, I has a girlfriend who was not exactly bad at math (we were in
the same differential equations course; she was scoring higher on the
tests).  She knew nothing about computers, though.  She pointed out
something she was sure was an error in a FORTRAN program I was writing:

    X = X+1

To her, this was impossible.  I tried to explain assignment, but I think
she was still puzzled in the end.

Erlang "assignment" is really more like a kind of equation solving.  To
the extent that people new to programming have any mathematical
intuitions or skills they might bring to bear on learning the skill,
Erlang would seem to be a better match to what they learned in their
basic algebra classes.
