Any plan to add async?

Hi,

I'm reading the docs and it seems to be a very interesting language, but I can't find anything related to async.

It's mentioned here: https://c3-lang.org/faq/compare-languages/#in-zig-but-not-in-c3 but it seems to indicate that it does not have async now.

When 0.6.3 is feature complete and async is not there, so what's the plan for async?

There are no plans to add async at all, and this is completely deliberate.

thanks, it would be nice to add it to https://c3-lang.org/faq/rejected-ideas/

I don't know how to write a compiler, but I was wondering, can compilers be configurable? like some lint tools (https://eslint.org/docs/latest/use/configure/)

In that way, it's easier to put some features configurable to the users. For example, if someone does not like goto, he can configure to disable it; if someone else likes async, he can configure to enable it.

It must be difficult because I have only heard one compiler like https://github.com/seanbaxter/circle/blob/master/new-circle/README.md#feature-directive-philosophy

I don't think its necessarily extremely difficult, I think it just adds a lot of unneeded complexity. It also makes the grammar somewhat ambiguous which can make debugging more difficult. Also with adding async as part of the language, it can make the resultant binary harder to predict. C3 and C both try to be fairly explicit about what is going on (C3 has more abstraction but it still has more control than something like rust) hence the reservation in adding it. Also it is possible to implement asynchronous code without special syntax for it, its just harder.
