Never used Python.  Have used APL and J.
Interesting representations of some mathematical concepts.

The system is written in a language.  Assembler, Oberon, C depending 
on the system.

How is a more abstract level of problem tackled?  Three possibilities 

(1) Design and create a library (or libraries) expressing abstract 
concepts in the system language.  Work on a problem using the system 
language and appropriate library.  Eg., the matrix project for ETHO.

(2) Design and create a language (or languages) incorporating abstract 
concepts.  Work on a problem using the appropriate language.  Eg., 
Python, APL, J;  in ETHO, the syntax of Oberon.Text is similar to JSON, 
Vinci expresses 2D graphics.

(3) A combination of (1) and (2).

Are (2) or (3) ever justified?  Merely personal preference?  
Quantitative argument?
