in thread Long regexp un multiple lines

Enlil (et. al.), one of the convenient things about qr// is that it returns a self-contained regex. That means your "later on" code can be /^$x{5}$x$/ It seems weird to me that there's no simpler way to say "pattern X, N times, with pattern Y in between"... you have to write /^(?:XY){N-1}X$/. I wonder if there's something in Regexp::Common for that.

    Actually the reason he had to use the (?:$x:){5} approach is because of the colon character that's supposed to delimit each grouping. Your solution leaves that out entirely. Yours will expand to: 
    /^(?:[\da-f]{2}){5}(?:[\da-f]{2})$/

    ...note the missing : colons.
