Title: avoid warning on 5.17.1

At least for now, 5.17.1 adds this warning:

Unescaped left brace in regex is deprecated, passed through in regex

Non-quantifier non-parameter braces need to be escaped. The { in a
qr{} can't be escaped for nasty tokenizer reasons, so instead the qr{}
here has been switched to a qr<>, clearing up the warning on 5.17.1
