Misc #20272: Ambiguity around Ractor message sending FIFO semantics
https://bugs.ruby-lang.org/issues/20272
* Author: forthoney (Seong-Heon Jung)
* Status: Open
* Priority: Normal
----------------------------------------
The docs should explicitly state the semantics/properties of Ractor message, especially
when it comes to FIFO.
For example, assume I have two Ractors, Ractor A and Ractor B. Ractor A sends two messages
`"hello"` and `"world"` in this order to Ractor B.
If I call `Ractor.receive` on Ractor B, am I guaranteed to see `"hello"` and
then `"world"` or is it possible the messages are delivered out of order?
