Good to learn about here strings. I've seen them somewhere but never paid
much attention.

For short strings I'd rather type things like "\\\\" than
#<<END
\\
END

Because the latter is more verbose and breaks the visual flow.

Both `#<<END' and `END' must come in their own lines, and no line breaks are
considered immediately after and before these tokens, respectively
(reasonable).


Many thanks for this thread! It deserves a post on my blog :D

BYE
