Or use:

Instead of the more correct:

Well, close takes exactly 1 parameter, so the first variant is working
correctly.
perl -MO=Deparse -e '
close( SOCKET || die "amai" )
'
close SOCKET;
-e syntax OK
The code can start to fail if Perl would change the signature of close().
This is a nice example of why it is hard to remain backwards compatible.
By having the signature of close as it is, it can't be changed without
making "wrongly styled" code fail.
I also prefer to code it with 'or', and without using parens.
