How do weights work on Lark rules / terminals? #1491

I've googled around the docs and found no info on this and the issues forum posts about weights don't mention how they work.

So is .1 higher priority than .2 ?

I'm using Earley parser because the grammar is just too hard to disambiguate or remove collisions from when using LALR.

I was thinking of using weights on various math operators. E.g. * will always have higher priority than + because in math that's how things are done conventionally.
