Cited in APL and Julia threads as a neat way to run APL-style syntax at Julia's speed.

A JuliaCon 2016 talk by Shashi Gowda showing an APL implementation in Julia. APL code is translated to Julia and JIT compiled to machine code.

“I thought it was a pretty neat way to run APL.” (HN, 2018)

on HN thread Compiling a Subset of APL into a Typed Intermediate Language (2014) [pdf]

Reminds me of the APL interpreter in Julia ( [this video] ). The APL code gets translated to Julia data structures, which is then mapped to Julia code, which is then compiled to machine code via Julia's JIT. I thought it was a pretty neat way to run APL.

on HN thread Rust: The New LLVM

Once static compilation gets off the ground, I wonder if Julia isn't an easier target for "high level LLVM". The whole language is built to be extensible, and people are already using it in comparable ways. APL implementation: [this video] As a code generator for the Go assembler: [link]

on HN thread APL deserves its renaissance too

In fact, it can get extremely close: [this video] And since you can define your own operators, you could just go all of the way.

on HN thread APL – A Glimpse of Heaven (2006)

I just found that there's a Julia package for at least some APL syntax, perhaps an easy way to play. [3] is a fork updated for v1.0: [1] [this video] [2] [link] [3] [link]
