Justified Variables

I like it when my source code lines up nicely, don't you?

This document is here to

help
make
your
code
look
nice

Let's put an end to ugly pairings, such as open/close, alpha/beta, vertex/edge. Let's see more of open/shut, node/edge, push/pull!

These typographic constraints can make coding feel like a crossword puzzle.

justified variables are clusters of related words of the same length (justified in fixed-width font). We're particularly interested in word clusters with contrasting meanings, part-whole, antonyms, and frequently associated programming / math jargon (variables). Standard abbreviations are gladly accepted.
