I use on occasion sans for without. It has the advantage to consist of the same number of letters (great for nice code formatting). Also, writing without is 75% longer and I don't like it.
Of course there's w/ as an abbreviation but partly I wish to use full words (albeit short ones) and partly, consider the below.
Oh, so clever: with/sans $$$
Plain stupid: with/w/o $$$
My fear's that people in general don't understand the context of sans and/or that they find my text unnatural, though.
Example from coding world.
public enum Equipment
{
None,
With,
Sans,
Full
}
