MAP =

Canonical names use simple domains:

  • core.* : elementwise / structural ops

  • agg.* : reductions (sum, etc.)

NOTE: keep this lexical-only. Overload resolution (e.g. length on string vs array)

should happen in a later resolver pass.

{
  :+ => :"core.add",
  :- => :"core.sub",
  :* => :"core.mul",
  :/ => :"core.div",
  :% => :"core.mod",
  :** => :"core.pow",
  :"==" => :"core.eq",
  :"!=" => :"core.neq",
  :">" => :"core.gt",
  :">=" => :"core.gte",
  :"<" => :"core.lt",
  :"<=" => :"core.lte",
  :"&" => :"core.and",
  :"!" => :"core.not"
}.freeze
