What version of perl are you using? It works as posted for me running perl 5.6.1 on Redhat linux 8.

From perlre:

(??{ code }) WARNING: This extended regular expression feature is considered hi +ghly experimental, and may be changed or deleted without notice. A si +mplified version of the syntax may be introduced for commonly used id +ioms. This is a ``postponed'' regular subexpression. The code is evaluat +ed at run time, at the moment this subexpression may match. The resul +t of evaluation is considered as a regular expression and matched as +if it were inserted instead of this construct. The code is not interpolated. As before, the rules to determine wh +ere the code ends are currently somewhat convoluted. The following pattern matches a parenthesized group: $re = qr{ \( (?: (?> [^()]+ ) # Non-parens without backtracking | (??{ $re }) # Group with matching parens )* \) }x;

They say that time changes things, but you actually have to change them yourself.
