I wanted to do something like this initially, but the various 'skip bugs
prevent an efficient solution ... or so I thought. Turns out that if you
store each memo as a line of text, then:
file: open/lines/direct %memos.txt
memo: copy first skip file rowid - 1
works, even though the 'skip refinement [of 'open] and "at file rowid"
don't. So expect a new RebDB memo! datatype, with some limitations, in the
next couple of days (plus a few other goodies).
