Maybe someone can give a better answer, but this is my initial thought:

A Scala DSL should theoretically be able to implement any programming language, because it can create an arbitrary structure representing the syntax, and then evaluate it.
A Scala DSL was not able to accurately reproduce the APL syntax for many reasons, one of which is
'single quotes'

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

Invalid Scala.

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