Could APL be implemented in Scala as a DSL?

Question

There is a old computer language called APL. Could this be implemented in Scala as a DSL?

Answer 1

Someone could probably give a better answer than this, but this is my initial thought:

1. A Scala DSL should in theory be able to implement any programming language because it could build up an arbitrary structure representing the syntax, and then evaluate that.

2. A Scala DSL could not exactly replicate APL syntax for many reasons, one of which is that

   'single quotes'

can denote a string in APL, but not in Scala. Also (from the wikipedia page)

×/2 3 4

wouldn't be valid Scala.

I don't know how close you could get, though...

Answer 2

A Javascript implementation exists here: https://github.com/ngn/apl
