Dear Dan,

Maybe we should be moving this discussion to another list.
I've asked admin at common-lisp.net to create lisp-interface-library-devel.

It would be delighted to help with such an effort,
either a merge of the two libraries,
or a layer to make them work together.

Also, considering that LIL has so few users (just drewc and I, IIUC),
it is still time to rename basic API functions if you have strong opinions.

While adding support for concurrent data structures
has long been on my TODO list,
I admit I haven't given much thought on how to automate (or not)
whatever locking is required (or not) on various methods
(not the same methods, depending on the data structure).
So far, my hypothesis is that nothing needs to be changed
as far as the signature of map interfaces goes:
the underlying implementation may or may not be concurrent,
that doesn't directly affect the calling conventions.

Of course, concurrently accessing a non-concurrent data structure
may blow up in your face, but
I don't know how to express linearity constraints in Lisp, yet.
That's a topic I'm actively researching, though, and suggestions are welcome.

In short, I'd love that to happen, I'm ready to help, and
a small data structure library is the perfect place to start.
