I've been doing some more work with atspkg and polyglot builds. It is now in
slightly better shape, and it gives us the ability to call ATS code in Haskell
almost painlessly.
As astute followers of this blog will know, I have been working on several ATS packages for Haskell; here I would like to present the fruits of these labors: the ability to use Haskell's Dhall library in ATS.
ATS is an incredibly apt systems programming language; as it compiles to C it enjoys all the versatility that C does. In particular, this means that we get some flexibility from the ability to import from high-level languages as well as export to them.
I wanted to give a small demonstration of ATS, partly to document a little bit of how to use atspkg, partly to show how to (safely) beat C's performance in ATS, and partly an example of how to parse command-line arguments in ATS.
I came across some interesting benchmark results recently, and I figured I'd give a short writeup.
