Numeronyms are fun, but they have one major problem: namespace collision.

What is a11y? Is it accessibility? Associatively? Axiomatically? Autobiography?

This is obviously a problem that needs solving.

My solution? SHAsum hashing.

We can avoid the ambiguity of "a11y" with this unique, cryptographically sound alternative:

Accessibility? a884a5f3609f2cca635fed56d4ec5795da56fb970y

Axiomatically? a20c4bcee8f977a3f5a3b6b499d52d7dd32584771y

Simple, easy to visually distinguish, everyone wins.
