[kwlug-disc] WASI 0.3, combining async and sync code

[Mikalai Birukou]

This video https://www.youtube.com/watch?v=W3f8AAte0LM titled, "... 
Incrementally Extending WASI 0.2 to 0.3 and Beyond ..." has around 
minute 8, a point of how "what color are your functions sync/async" 
problem (async leaks and makes everything async).

Side note, similar can happen with ReactiveExtensions (rx), but move 
with human tendencies to make all same, rather then interfaces forcing 
it on you.
