I just realized: The tool "#make" is awesome when it's declarative and concurrent, and it sucks when it's #shell-like.

What else is declarative?

#Prolog!

Does anyone know a Prolog inerpreter in which concurrent calling is easy? I have something in mind...

@dcz ansible (async io loops are concurrent)

@ruff Ansible is completely sequental. I have never seen it execute multiple jobs at once.

I'd complain more, but this is already a deal-breaker :)

@dcz originally yes, but as i said aio loop construction is totally parallel. and main playbook could be a single loop calling modules with business logic. But that logic follows same principles, sequential unless aio-looped.
