the power of #rust in action.. an upgrade from nom 4 to nom 7 (yeah, I know) brought with it some breaking changes. like fundamental changes to the API and integration surface.
I thought I was looking at a full rewrite for my pet language (compiler, assembler, VM, repl) but it took all of a couple of hours, with the support of the robust testing, logging, and borrow checker frameworks.
in any other language this would have been a burn-it-down moment I think.
