From the error you got, it looks like you did something like:

match_regexp("foo","Class: []");

[ and ] are special characters in regexps and expect a list of valid 
characters or character ranges between them.  To match against literal 
[]'s, quote them with backslashes, e.g.:

match_regexp("foo","Class: \[\]");
