I just found this work @harris-chris
It looks amazing. 
Like John says, this is the future.
Ubiquitous functions. Callable by URL.
The AWS Step Functions is a primitive implementation of chaining arbitrary functions.
We need latency between functions to move closer to what they are when in the same runtime.
If we could wrap all the owner that is Julia into easily digestible lambdas, it would be easy for other to integrate into systems that have much more developed toolchains for this web world.
But this paradigm of polyglot functions is much bigger than that.
We have ongoing discussions with AWS and have brought this up.
Best wishes and thanks for this Chris
