Yes, that would make Chapel much more interesting. I think that 
being able to write libraries/engines in a new language and call 
into it from an established high-level language is a good general 

Often times language authors see their language as the host 
language and other languages as "subordinate" library languages. 
That is probably a strategic mistake. It is kinda sad that so 
much open source library features have to be reimplemented in 
various languages.

You could write up your ideas and create a blog post that 
describes it. I believe there is a reddit for people creating 
their own languages, could inspire someone?

Ah, interesting, Polaris used network-on-a-chip. According to 
some VLSI websites the Polaris led to Intel's 
many-micro-cores-on-a-chip architecture, which led to Larrabee 
and Xeon Phi. Last version of Phi was released in 2017.

Another type of many-micro-core processors with some local memory 
are the ones geared towards audio/video that use some kind of 
multiplexed grid-like crossbar-databusses for internal 
communication between cores. But they are more in the DSP 
tradition, so not really suitable for actor-style languages I

Pony claims to be deadlock free:

I assume that you could still experience starvation-like 
scenarios or run out of memory as unprocessed events pile up, but 
I don't know exactly how they schedule actors.

Yes… just like Php…
