On a related note, have there ever been extensions for PosgreSQL/SQLite/any other FOSS DBMS that would allow using Tutorial D[1] (the Third-Manifesto one, not to be confused with Walter Bright's D language) to define and query data? In particular, I feel like PostgreSQL's CREATE TYPE[2] feature would allow for easier bridging between SQL and Tutorial D. Unfortunately, searches for “PostgreSQL Tutorial D” don't issue useful results for obvious reasons.
