    Yeah, Net::Telnet is rather old and uses a weird method of passing regexes as arguments. For a more recent module qr// would be appropriate, but Net::Telnet requires a string that starts and ends with a slash.

    The other posters are right when they say you should double quote. Any method for building strings will work:

    '/'.$username.'/' "/$username/" sprintf('/%s/', $username)
    As an aside, if you're trying to log in, there's a login method in Net::Telnet.

[Corion]: Hmm. I think overnight I decided on simplifying some code. I have plugin classes that do data import (.csv, .yml, .json) and for that create objects on which then ->load() is called. But YAML::XS doesn't have an object, so I wrote my own wrapper.
[Corion]: This evening, I'll kill that wrapper again, and just call LoadFile() in the plugin class directly instead of creating a go-between object for no real gain.
[Corion]: Writing these import plugins was really nice though - in about 2 hours, I had imports for CSV, YAML and JSON, and adding XLS(X), SQLite (or DBI) data sources is also trivial. I'm idly wondering about separating the plugin into transport+parser, so ...
[Corion]: ... http:// URLs could be retrieved and then parsed, but I think that that would be overkill for a toy static site generator ;)
