Subject: RFC: expand $'' within heredocs
Date: Wed, 28 Sep 2022 16:30:26 -0400	[thread overview]
Message-ID: <5701a51d-76ff-240a-929c-054460841e80@gmx.com> (raw)

Hey all,

bash 5.2[1] recently released and a change i found of interest is allowing $'' to be expanded
within heredocs. $'' is currently the only expansion that uses the `$' operator that doesn't
expand within heredocs(even $[] does); so i can see that edgecase being confusing in addition
to the feature just being useful.
cat <<eof
hello$'\t'world
eof
...

Not to bandwagon other shells, i just like the idea.
