Editing the language module is super slow

[FroMage]

At first it's fast enough, but after a few hours/days it takes 2 seconds per character typed and just hangs a lot, and blocks the whole editor, I can't even move the cursor while it's locked. Nothing shows up in the progress window.

Is this seriously for 1.2, @davidfestal?

[davidfestal]

I'm surely not against pushing it towards 1.3, if @FroMage agrees.

[davidfestal]

since editing ceylon code in a non-ceylon project is not a standard use.

[gavinking]

Exactly.
