That's one of the reasons RFC 9485, "I-Regexp: An Interoperable Regular Expression Format", is important.

Is .map specialcased or do user functions accepting callbacks work the same way? Because you could do the Scott-Mogensen thing of #ifTrue:ifFalse: if so, dualizing the control-flow decision making, offering a menu of choices/continuations.

(1998). Java existed, but neither Scala nor Java-with-generics did.

From the conclusion:

"We have presented a programming protocol, Extensible Visitor, that can be used to construct systems with extensible recursive data domains and toolkits. It is a novel combination of the functional and object-oriented programming styles that draws on the strengths of each. The object-oriented style is essential to achieve extensibility along the data dimension, yet tools are organized in a functional fashion, enabling extensibility in the functional dimension. Systems based on the Extensible Visitor can be extended without modification to existing code or recompilation (which is an increasingly important concern)."

Strange protocol. Why not pass a path to a file that should be `touch`d and/or written to, I wonder? Would avoid the complexity of sockets.

Per RFC 8259:

      ws = *(
              %x20 /              ; Space
              %x09 /              ; Horizontal tab
              %x0A /              ; Line feed or New line
              %x0D )              ; Carriage return

The analogous would be the Go-style represent-a-sum-badly-as-a-product,

  struct nonzero_t {
    int is_negative;
    unsigned int one_less_than_the_absolute_value;
  };

which, under interpretation, ranges from -(2^32) to -1 and +1 to +(2^32).

It's perfectly possible in languages with ordinary ADTs.

  data Nat = Z | S Nat
  data NonZeroNat = OnePlus Nat
  data NonZeroInt = Negative NonZeroNat | Positive NonZeroNat
