Antiquotation (
${expr}
) is supported in indented strings.
Since
${
and''
have special meaning in indented strings, you need a way to quote them.${
can be escaped by prefixing it with''
(that is, two single quotes), i.e.,''${
.''
can be escaped by prefixing it with'
, i.e.,'''
. Finally, linefeed, carriage-return and tab characters can be written as''\n
,''\r
,''\t
