I believe it would be nice and fun for readability if identifiers could be suffixed with any number of the following symbols:

' - prime (math notation for indicating values derived from other values)
? - question (for functions that answer a question. anything that returns boolean)

This is inspired by Ruby. We have ? but not Ruby's !, because it's the boolean NOT operator, and it wouldn't really solve anything—since haku does not have mutation at all. Maybe it would make sense for acts, as they represent side effects—like plotter! or stroke! but I'm not sure that gains us any readability. It just looks weird.

Example with the builtin/dashes brush:

withDotter \d ->
  visible? = mod (d Num) length < length * duty
  if (visible?)
    stroke thickness color (line (d From) (d To))
  else
    ()

Example with the `builtin/dashes` brush: ``` withDotter \d -> visible? = mod (d Num) length < length * duty if (visible?) stroke thickness color (line (d From) (d To)) else () ```

riki changed title from ~~Symbols as identifier suffixes~~ to Additional identifier characters (prime ' and question mark ? suffixes)
