in thread using split

There is one subtle difference between using '...' and /.../ as regex delimiters. The latter interpolates where the former does not. That does not affect the examples in this thread though.

    And the difference between "..." and /.../ is that "..." unescapes too much.

    For example,
    "\d" is the same as /d/.
    If you want /\d/, the equivalent would be "\\d".

    I always use /.../ or qr/.../ to avoid confusion.

      Yes. I never use "...", preferring m[...] instead. Using '...' for a regex is simply shorthand for m'...' which gives the same, non-interpolating behaviour.

      A bad habit? Maybe...
