Microgroove supports type-safe positional heterogeneous records similar to vinyl and SOP.
Microgroove can be used for lightweight statically specified polymorphic records just like vinyl, but also dynamic record types that are only provided at run-time, such as receiving an arbitrary JSON protocol.
The recommended way to build microgroove is via stack with stack build
Array-backed records have been merged into vinyl as ARecs! Please continue to contribute further development there.
