Bug #34303 for JSON-XS: perl regexp character classes treated as escape sequences

Hi,Great module, really. Well, not sure if the following is a bug or a feature, but I really would like to be able to store perl regular expressions using JSON::XS. Imagine the following code: { "alias":{ "match":"m|^[\w]+$|" } } When parsing the file I get the following message: illegal backslash escape sequence in string, at character offset 121 ["\\w]+$|",nn ..."] at ... which made me to rewrite my regex like this: "match":"m|^[:alnum:]+$|", This is a workaround for now but I may see my self forced to turn back to YAML or simply Perl. Thanks in advance. This is the most impressive serialization module I used.
