A very minor note on this - i usually caution people in the classes i
run to include a literal string whenever they use ||
B B B B $a || $b || ""
The reason is human - in JavaScript, C, C++, Perl, Python, bash, awk,
many other
languages, B || is a boolean operation that mirrors &&, and if you look
quickly at an expression you can get very confused.
