Update "How and why do C<say>, C<put> and C<print> differ?"

  - the text predated the invention of "dd", add that to the mix
  - "dd" is intended for debugging, "say" is intended for human interpretation
  - the wording on how a type object is gisted, was wrong (the example was correct)

TimToady huh, I think our dwimmery is just a bit off there 19:58
timotimo can we do this right without resorting to backtracking? 19:59
moritz no 20:01
well, maybe with copious amounts of look-aheads
TimToady it's already failing when it can't find the '>' 20:02
timotimo no need to two-pass parse if you're parsing two alternatives at the same time ...
TimToady we just need to throw a '='? in there and include it in the message, or so
timotimo oh, *that* is what you're refering to
TimToady yes, it currently checks what follows the < to see if it looks like a likely comparison term 20:03
<?before \h* [ \d | <.sigil> | ':' ] >
I mean, we could just add '=' to that list, but then it would misleadingly claim that an intended <= is really a < operator 20:05
timotimo don't forget about <==, too
and also <<==
TimToady well, those are much less likely to have spaces omitted around them, and also much less likely to have a sigil or number after them 20:06
so I doubt the heuristic would be useful in those cases very often 20:07
20:07 Kaiepi left
TimToady and the main problem is people coming from other languages where they're used to getting away with no spaces around < or <= 20:07
