Unless you have one of those new fangle nueral net
hardware systems, I believe that it has to evaluate
each match one at a time.
If it doesn't I'm very curious on how it can jump
to any of the arbitrary conditions without testing
for them.

If it doesn't have a break it should go on to the next
condition and run it if it matched (of maybe I'm wrong and
jumps to the default). But I think I'm right.

:) like I said, cases are bug cities.

SWITCH: {
if /blah/{
&blah;
last SWITCH;
}
if /blahi1/{
&blah1;
last SWITCH;
}
if /blah2/{
&blah2;
last SWITCH;
}
if /blah3/{
&blah;
last SWITCH;
}
print STDERR "\nYo - this aint supposed to happen!";
exit;
}
There is problibly a short syntax with commas
