[S02] {Note however that bare circumfix or postcircumfix <<...>> is not a
user-selected bracket, but the ASCII variant of the «...» interpolating word
list. Only # and the q-style quoters (including m, s, tr, and rx) enable
subsequent user-selected brackets.}
Just to clarify on that quote from S02, what I was trying to say (if I
understand the synopsis correctly) is that << counts as either single or
double depending on context. If you stick a # on the front, then << will
count as a double bracket.
Thanks for the clarification. Either we change this so that '<<'
counts as a single bracket for inline comment purposes, or we live
with the risk of start-of-line inline comments '#<< ... >>' when
prepending #'s to comment out sections of code.
Or we leave it as is. Is it really _that_ big of a problem to retrain
yourself to type "# " instead of "#" when commenting out lines?
It would certainly annoy a lot of people, me included! :-)
Here's a radical notion: use something other than '#' to initiate an
inline comment.

Or maybe just don't allow "embedded" comments unless they are actually
"embedded", i.e. if a line starts with a # (ignoring leading whitespace)
then it's _always_ a line-end comment, no matter what follows the #, e.g.
#blah # line-end comment
#{ # another line-end comment
#{ # yet another line-end comment (YALC)
some-code-here #{...} # embedded comment
If we allow the following coding style from S02:
#sub foo # line end comment
#{ # okay, comment
... # extends
} # to here
then perhaps we should change the term "embedded comment" to "extended
comment".
We could always have a Q form in place of #'s to achieve the above
effect from S02, more like a funny heredoc, e.g.
Q :#<<< # embedded
sub foo # comment
{ # extends
... # to
} # (wait for it)
>>> # here!
Maybe call it a "theredoc"! :-)
Cheers
