The Language Roadmap

Pometo is a reimplementation of a venerable programming language paradigm apl (which stands for Another Programming Language imagine the brass neck of that for a name?).

The aim is to make a janus-faced, pure-functional, auxiliary (or lambda) language:

• looking towards Erlang, Elixir and LFE it is a native BEAM language that can handle native data types
• looking towards apl it is a normal apl implementation

We therefore have some prejudices:

• conforming to the current version of Dyalog APL (18.0) requires no special decision making
• deviating from or extending the language from that base requires an explicit decision to do so
• Pometo is not a concurrent language - it runs inside a single BEAM process - concurrency comes from being embedded inside an application writen in Erlang, Elixir or LFE. This means that Pometo will never have what are traditionally thought of as core BEAM features:
  • no OTP/supervision trees
  • no message passing
  • no side effects - it is a pure functional language

There are some great Dyalog resources:

• a manual
• a live REPL
• a live help site
