Making sense of terrible template errors with 'camomilla'
summary
Command line tool camomilla is a small Python script that rewrites fat C++ template errors by collapsing template arguments to configurable levels so deeply nested types become readable. It supports depth-based collapsing with incremental expansion, caches previous expansions so reprocessing different depths does not require recompilation, and simple alias/reject rules to hide common wrappers. Works on real Boost-heavy code (transcript mentions boost Hana and Busan PL) and reduces compiler output size enough to make debugging practical.
