"------------"
\' (["\\\']) Matches a " or a \\\' and stores it in \\1\'
\' ( starts \\2\'
\' (?: starts a non-capturing group\'
\' (?=(?:\\\\)*) Will check if there is an odd amount of \\ \'
\' \\\\. will escape / ignore it \'
\' |. will never mind it if there\\\'s an even amount \'
\' )*? will close the non-capturing group and repeat it\'
\' \\1 will make it close with the quote selected in \\1\'

# print "Capture Group 2 is $2 ... and so on\n";
}
# ${^POSTMATCH} and ${^PREMATCH} are also available with the use of '/p'
# Named capture groups can be called via $+{name}
