gollark: It's not a DFA, it uses a GTech™ regex turing machine to implement Macron to do this.
gollark: Or the osmarks.net source code.

gollark: I use some of this sort of tooling and you basically write stuff roughly as normal.
gollark: Nobody is going around manually editing stuff with those randomly generated names, you realize.
