This is a pre-alpha announcement of an SQL engine implemented on top of MetaKit.
More languages are a very definite option.
MkSQL was implemented entirely in Python by Gordon McMillan, on top of the Mk4py binding - in which he also played the leading role. Many modules were dropped, including the parsing and compilation subsystem, this thing only runs compiled Python bytecodes. But we think we know where the time is spent, and have several tricks up our sleeves to fix that. Speed will come later. The purpose of this announcement is to gauge the interest among current MK users, and to get in touch with a few people who might be willing to help with suggestions, testing, and tuning.
