What's the story behind the ::'s sometimes token name
T_PAAMAYIM_NEKUDOTAYIM
I'm mainly interested in knowing if
- This is an abbreviation for something else.
- This is a phrase in a language other than English, and if so what's the language and what's a rough translation.
- This is some obscure-to-me programming term.
- Drunk developers.

From the PHP docs:
Paamayim Nekudotayim would, at first, seem like a strange choice for naming a double-colon. However, while writing the Zend Engine 0.5 (which powers PHP 3), that's what the Zend team decided to call it. It actually does mean double-colon - in Hebrew!

It's the scope resolution operator.
