[erlang-questions] exported variables
Sat Jan 19 11:43:45 CET 2019
Some time after that discussion, the compiler was changed to warn only for
those variables that occur in a pattern and are exported from an above
case/if/receive/try. So you can export a variable from the clauses of a
case and then use it in a computation without complaints from the compiler,
but if you use it in a match, you get a warning because it's likely that
you thought it was actually free.
