I don't write Picat, but when I write Prolog the color scheme for Emacs gives those operators a bright color so they stand out.

Right. As someone who uses raindbow parentheses, I should have immediately thought that it would be solved by the editor. Still, I don't like if readability relies on the editor too much, since you often want to paste or read code elsewhere (on HN, stackoverflow, github, random websites, etc) that may not know about your non-mainstream language.

  if making your editor compensate for the language syntax is the only way to make the language syntax easily readable then the language designer has failed.

    The comma and dot are natural ways to separate and end statements in natural language. Why are they a problem in a programming language, where you have to be extremely careful about your syntax anyway?

      I think there's two reasons: First, its a trend. Other languages have trained us to not see them so much (as pard68 said), to put much more weight on other things. Its not complete though, many programming languages do use them: to separate elements in a list, to separate parameters, as method.calls, and in numbers 1.0, so that's probably a very minor reason over all. Second, programming languages are very symbol heavy: we use all kinds of operators and special->symbols and (various [brackets]), it just kinda drowns out small symbols that are at the bottom of the line like a , or . and they're just not as obvious as keywords or ink-heavy symbols. But overall, I guess I'm just not used to seeing them in that context and I'd get over it really quickly, just like I very quickly got over Python's significant whitespace or Lisps parentheses. It seems like a big deal until one day suddenly its not anymore.

And the compiler gives a bright (red) color to their absence, also. You do need the Swi-Prolog IDE for that though.
