Dull

The language is dubbed "dull". Dull, because it is a less featureful ES6. Where does it differ from ES6?

  • No 'with'
  • No 'eval'
  • No promises, async, await, generators ...
  • Names can include any character
  • Automatic tail call optimization
  • No class syntax, at all
  • No null; only undefined
  • No import/export syntax; 'use' instead
  • No proxies
  • Strings demarked with "" or `` only; ' is reserved for symbols, akin to scheme. 'ok is shorthand for Symbol.for("ok")

Eventually, it could be JIT'd, but another trait of dull is that it is easy to integrate C code into.

Dull is based on Javascript, and has C-like syntax, because that makes it trivial to push code from it into a real C file. Numerous times I've been able to nearly copy and paste some dull code into a C file and get an immediate 50x speed improvement.
