Enhancement proposals

  • Add dsl (domain-specific language) literals; what keyword?:

      const buf = dsl(buffer)(1234abc)
  const re1 = dsl(re)/.*/
  const re2 = dsl(re):.*:
  const re3 = dsl(re){.*}
  const re4 = dsl(re)<.*>
  const re5 = dsl(re)(.*)
  const sh  = dsl("glsl"){ main() { outColor = vec3(1, 0, 0.5) } }

  • Add 'static' members in classes.

      class fruit {
      static var type = "apple" # fruit.type = "apple"
      static fun get_value { return 0 } # fruit.get_value = fun { ... }
  }

  • Add 'enum' syntax sugar for multiple, consecutive integer constants.

  • Allow invoking functions declared anywhere in current and outer scopes.

  • Optimizations:

    • Find line where a variable is no longer used, release register.
    • Don't reload constants if they are already in registers.
    • Hoist constants outside of loops. Reuse constants.
    • Function inlining for simple functions, esp. inside loops.
    • Stack reuse in tail calls.
    • Replace binds for non-global functions with LOAD.CONST
    • Init arrays/objects from a constant, by doing a deep copy (only works for some initializers, which don't reference other objects, etc.)
    • Make r255 a VOID object
    • References 127 constants via r128..r254 (LOAD.CONST 0 is then constant 127)

  • Close generators by throwing an exception through the generator code during GC

  • Allow _ in parameters of the target of -> stream operator

  • Add warnings about variable shadowing, consider making shadowing an error

  • Add a way to extract list of modules

  • Add string.prototype.swapcase()

  • Add exit/help as special commands in REPL or as functions in a special module

  • ? Comparison operators for objects

  • ? Add match expression

  • ? Add delete global in REPL (only), set BADPTR on global, functions using globals should then fail

  • Expand object in-place, e.g. { a: 1, b..., c: 2 }

  • Add syntax coloring for VSCode, Eclipse, IntelliJ IDEA

  • ? Remove //-style single-line comments

  • ? Change division to produce float, add integer division operator, e.g. //

  • ? Add buffer strings b"" or buffer literals <01 fa>

  • ? Empty array, buffer, string, object (shallow) are all falsy

  • ? set/get:

      var myobj = {
      prop: set fun { },
      prop: get fun { }
  };
  myobj.prop = set fun { };
  myobj.prop = get fun { };

  • Constructor functions - determine interaction with generators and iterators.

  • Fix string comparison, compare by code point value.

  • Add unicode module for string comparison, uppercase/lowercase, etc.
