I have been.

Though, in this particular case, I needed to dig all the way down to LMDB
page layout to grok key indexes, compare to mdb_cursor_next, search for
instances of C_DEL, etc. to understand what was happening.

Reading code works better when we have something more modular and
compositional, i.e. such that you can read and understand in small pieces.
LMDB is just one big module, you can't understand most pieces without
seeing the whole picture. This isn't a bad thing for its purpose, but it
does mean good API documentation saves hours or days of reading code for
someone who wants to just use LMDB.

Then make it so. It will save a lot of people a lot of time. :)
