Question about || (was REGEXP removing - il- - -b-f and - il- - - - f)

Why is that? :) I was actually going to post a question about ambiguity
syntax later, but here it is anyway. Are the following 4 equivalent?

1)
if ($b) {
$a = $b;
}
else {
$a = $c;
}

2)
$a = $b or $c;

3)
$a = $b || $c;

4)
$a = $b ? $b : $c;


Also there was an example on the web that completely threw me off. Although
this works:

local ($/);

,I have no idea how it undefs $/. Points to a good reading on the
subject are equally appreciated.

Thanks

Sorry about this last one, I undrestand the idea of local for globs, I just
thought that

local $/;
and
local ($/);
differ. While reading your answers I realised that it's the same as saying:
my ($a); which is equivalent to my $a; It is pretty weird to have equivalent
operators ( 'or' / '||' ) with different precedence. I guess this is where
