I don't know if it is clear in the docs anywhere wrt regex, but the
string literal parser will consume one layer of backslashes on you. So
in your first case '\\d' is fed into the regex matching function as '\d'
(string literal parser sees \\ == escape \ == \), and in the second case
'\d' is fed in as 'd' (string literal parser sees \d == escape d == d).
The basic rule at work here is you need to double up all backslashes.
