This doesn't do 'the right thing' for strings starting with a newline (which admittedly is a border case): `perl -MData::Dumper -e "$foo=qq(\nHello);$foo =~ s/.//; print Dumper \ +$foo"` [download] Adding the `/s` flag makes dot match newline too: `perl -MData::Dumper -e "$foo=qq(\nHello);$foo =~ s/.//s; print Dumper +\$foo"` [download]	[reply] [d/l] [select]
