Oops, the last example should have been:
over (chunksOf 3 . individually) (<* yield 0) (each [1..10])
... and now `lens-family-core-1.1` works correctly with the
`individually` lens.

Apologies for what's probably a fairly newbish sort of question: I'm
trying to write an efficient pipe for direct-sqlite.
While I could run each insert in a separate transaction, this would
kill my performance. Thus, I'm trying to find a way of saying "give me
everything you have available right now, up to a maximum of N writes".
Nick Partridge pointed me to pipes-group, and chunksOf in particular
looks interesting but I'm having some trouble understanding how to use
it. Could anyone give me a pointer?
(In this case, it is actually a pipe rather than just a consumer,
because I need to notify another part of the system that the write has
finished.)
cheers
