[erlang-questions] erlang sucks

[Lennart Öhman]

I am compelled to "help" Sean. Further, I feel there is a difference
between to pattern-match a branch decision, and to do logical tests.

Example of perfectly legal but in my opinion ugly code (where 'if' or
using guards in a function-head of a help function is the correct
solution):

case X of
        X when X>10 ->

:-)

No, no no! I like 'if' It allows some neat constructs that are
horrible with case.

Counting 'if' and 'case' for one of the apps in our codebase gives
this result:

alex:src sean$ grep -v '^[[:space:]]*\($\|%\)' $(find . -name "*rl") |
grep " if " | wc -l
      345
alex:src sean$ grep -v '^[[:space:]]*\($\|%\)' $(find . -name "*rl") |
grep " case " | wc -l
     1052

~ one quarter of branching constructs are 'if'. Not at all
insignificant.
