The new S2 says:
# Heredocs are no longer written with <<, but with an adverb on any other
# quote construct:
#
# print qq:to/END/
# Give $amount to the man behind curtain number $curtain.
# END
Does "any other quote construct" include rx//? I've wanted that for a
while in Perl 5 (although with anonymous rules, I suppose it's no
longer that important...).
# In order to interpolate an entire hash, it's necessary to subscript with

# print "The associations are:\n%bar<>"
Am I to assume you can use empty French/Texas quotes, too? (i.e.
%bar«» or %bar<<>>).
This paragraph also made me realize: am I the only one who foresees
somebody doing this?
$OUT.printf("We produced <b>%d</b> somoflanges this month!\n", $content);
(Granted, the fix is trivial--just replace the double-quotes with
single-quotes, or add some of that optional spacing HTML lets you
splatter around--but it seems like an easy mistake to make.)
Finally, I noticed that the "Files" section only talks about iterating
over all lines. Do you have a decision on single-line reads yet?
[And a note to the editors of dev.perl.org: can we get tables of
contents on these documents? While it's nice to exercise Firefox's
slick find-in-page interface so much on, say, Apocalypse 12, it'd be
more convenient to just have a TOC.]
