in thread prompting a user for input

You probably want to anchor that at the ends, otherwise 'abcNOdef' and 'blahYblah' will match. Also, the parens around the single char 'o' are unnecessary. 
/^(Y(es)?|No?)$/i

    matches y or yes without any regard to case and doesn't store the match in $1 unnecessarily. TMTOWTDI
