I would assume they want a numeric value. In which case, using \d is
wrong, as \d matches several hundreds of different characters - and only
10 of them are considered numerical by perl.
(If we ever want a warning on existing behaviour, I vote to warn on any
use if \d. Most of the time, the author intends [0-9], which hasn't been
equivalent to \d for quite some time).
