Did you know that Factor has a boa constructor? Yes, you read that right, not a "constrictor", but a constructor.
From Slava's blog:
construct-boais a low-level word taking a class; BOA denotes "by order of arguments", and "BOA constructor" is a pun on "Boa Constrictor", one of the more amusing pieces of terminology in use by the Lisp community.
It's apparently an old Lisp joke, but it gave me a chuckle today as I was hacking on some Factor code.
