LVCA (Language Verification, Construction, and Analysis) is a toolkit for building programming languages. Well, it will be. Right now it's a collection of ideas and prototypes, available below.
Writing
These are meant to form a somewhat coherent story, read in order. They'll be updated as LVCA evolves.

These are shorter, more frequent posts. I won't change these in a major way after they're published, so they can serve as a progress log. The newest posts are at the top.
