Take a look at ConcurrentML and its implementations in Racket and Guile. Schemes have stackful coroutines (as a side effect of supporting delimited continuations), and CML builds green thread like semantics on top of that with a small set o

I'm not sure how efficiently it compiles, but Racket's match form is implemented using macros and is stunningly powerful! https://docs.racket-lang.org/reference/match.html

I would like to disagree with this view of Racket. I'm a fairly experienced professional programmer with a lot of systems experience, and I find Racket an extremely well thought out, competently implemented and high performance (partic

Async/await is a _concurrency_ mechanism, and concurrency is certainly naturally useful. However async/await is certainly not the best implementation of concurrency, except in the narrow design space Rust has chosen. If you have a

One option is to write your language as a transpile to Racket and then leverage the existing ChezScheme implementation for performance. Racket is usually faster than Python although initial process startup is slightly slower than CPython.

Great summary. This paper from one of the Lua creators digs into this in the paper Revisiting Coroutines. It is a very readable paper. https://www.inf.puc-rio.br/~roberto/docs/MCC15-04.pdf

I don't know if the sort of deep refactoring and other integrations they offer in their IDEs would be possible in the LSP protocol as it exists today. I believe debuggers for vscode have a similar DAP protocol. Any way, my point is, th

I am aware of epoll_wait and friends (select/poll) accepting timeouts, and how that plugs into a general event loop like in libuv. However if memory serves, these calls are reasonably expensive (on the order of microseconds, and _worse

The crucial operation here is epoll_wait, not epoll_create. Are you saying that the system call is performed on another kernel thread while goroutine continue running on the GOMAXPROCS threads?

by nsm 3y ago
I feel like this glossed over how when entering something like epoll, Go can optimize switching to another goroutine. Wouldn't the epoll block until the calling kernel thread had a file descriptor ready?

IMO a couple of cool aspects of Racket that aren't called out in beginner guides, but I think are really useful in real programs: 1. The use of custodians on a per-(green-)thread basis that brings "oh yes, if the thread crashes or
