in thread using split

There is no difference in the two lines you listed.
perl -MO=Deparse -e "split('|', 'ab|c');" split(/|/, 'ab|c', 0); -e syntax OK

    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.


    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

      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...
