We may support string and char literals, and make a non-builtin library for string manipulation (via language extension).


  • Make it possible to write parsers and pretty printers in Arend (like agdarsec)
  • More flexible input to tactics -- we can pass some textual information
  • A step towards reflection API in Arend (accessing Arend AST in Arend -- in other words, quote/unquote)


  • Conversion between string and char list is very common, but if we want to support this, we also want to prove that such conversion is an isomorphism. If we built-in this axiom, we need to built-in the list type
  • One more AST type for concrete and core
  • This has few things to do with theorem proving, which is the current major focus of Arend

Strings can supersede chars. I'll finish strings
