Conformist is a pattern matching library, that i started as a part of my CAS.

As a real programmer i don't present realized features, i speaking about my plans.

1. Pattern matching for S-expression with placeholders, like :symbol, :list and another.
2. Flexible system of placeholders.
3. Pattern grouping (see chapter "thoughts" in org-file).

Very simple library, but soon i will expand it.
