I've been a professional C, Perl, PHP and Python developer.
I'm an ex-sysadmin from the late 20th century.
These days I do more Javascript and CSS and whatnot, and promote UX and accessibility.
If someone asked me to swap "two variables" and suggested that as an answer, I'd say my first variable contained the string "hello world" and the second one an array of types of cat.

Xor'ing those two might result in a cute internet meme. :)
