But I guess we currently need to supply things like Zlib_jll in the Project.toml [deps] section?
Mosè Giordano  6 days ago
Yes, exactly. The way the jll packages work doesn't allow them to be installed in julia <1.3, I don't see many options at the moment to make BinaryProvider and jll coexist in those versions of julia
Chris Foster  6 days ago
I see one possible option: the jll packages themselves could allow installation on julia < 1.3 and just load as an empty module in that case. That would allow some recourse for maintainers who have to support older julia versions.

Current notes are in my fork of the Juleps repo at
https://github.com/c42f/Juleps/blob/cjf/structured-concurrency/StructuredConcurrency.md
but most people seem to ignore the main Juleps repo so I haven't sent a PR yet (also it's very WIP).
We could move the notes to Jameson's julep wiki or somewhere else more conducive to collaboration? (edited)

This is nicely written -- good literature survey.

I'd be very interested in your (or anyone's) thoughts on Erlang's approach.
