You can lift the struct inside the parens to reduce the duplication, too.

regexp::common::balanced
Regexp::Common::balanced(3) User Contributed Perl Documentation Regexp::Common::balanced(3)
NAME
Regexp::Common::balanced -- provide regexes for strings with balanced parenthesized delimiters or arbitrary delimiters.
SYNOPSIS
use Regexp::Common qw /balanced/;
while (<>) {
/$RE{balanced}{-parens=>'()'}/
and print q{balanced parentheses
};
}
DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface.
Do not use this module directly, but load it via Regexp::Common.
$RE{balanced}{-parens}
Returns a pattern that matches a string that starts with the nominated opening parenthesis or bracket, contains characters and properly
nested parenthesized subsequences, and ends in the matching parenthesis.
More than one type of parenthesis can be specified:
$RE{balanced}{-parens=>'(){}'}
in which case all specified parenthesis types must be correctly balanced within the string.
If we are using C{-keep} (See Regexp::Common):
$1 captures the entire expression
$RE{balanced}{-begin => "begin"}{-end => "end"}
Returns a pattern that matches a string that is properly balanced using the begin and end strings as start and end delimiters. Multiple
sets of begin and end strings can be given by separating them by "|"s (which can be escaped with a backslash).
qr/$RE{balanced}{-begin => "do|if|case"}{-end => "done|fi|esac"}/
will match properly balanced strings that either start with do and end with done, start with if and end with fi, or start with case and end
with esac.
If -end contains less cases than -begin, the last case of -end is repeated. If it contains more cases than -begin, the extra cases are
ignored. If either of -begin or -end isn't given, or is empty, -begin => '(' and -end => ')' are assumed.
If we are using C{-keep} (See Regexp::Common):
$1 captures the entire expression
