Do you think D would benefit if you add this (or similar) feature to it?
Sean is working on a message passing (CSP) package for D. I'm not
convinced it needs to be a core language feature, though.
This is true. After I created ParallelFuture (the lib w/ parallel foreach, map,
reduce), a friend mentioned that my model was pretty similar to the OpenMP
model.
I read a little about OpenMP and it really hit home how powerful a language D
is,
given that I was able to implement something OpenMP-ish as a pure library,
without
any modifications to the compiler. The fact that message passing is built into
Go! makes me wonder if there's a reason why it can't be done well in a library.
Most stuff can be done decently well in a library -- imagine Plan 9’s
libthread with channels implemented input/output ranges. Select is ugly
though, without some language support; perhaps D’s compile-time stuff
can implement a select block.
