nonsense ... Did the possibility to insert no autovivification change the language?

    Man, you really don;t think things through do you.

    A configurable pragma won't speed numerical increment up, it'll slow it down. It's just one extra test that will need to be performed every time.

    And it won't help a JS port, unless the JS port will only run code that disables all the things that come from having transparent type conversion.

    That includes things like 2**32 (or 2**64) + 1 becoming an NV; and 0+'12' doing the right thing. And at that point; it ain't Perl.

      contrary to you, I do a lot.

      > A configurable pragma won't speed numerical increment up, it'll slow it down

      It already tests if the scalar is an integer or string, only in the rarely used latter case you need to check the flag

      > JS port will only run code that disables all the things that come from having transparent type conversion

      nope, the author is free to enable slow magic increment

      > 2**32 (or 2**64)

      you like contradicting yourself? if Perl can live with different integer sizes why shouldnt a JS port.

      Perl versions are never 100% compatible.

      > 0+'12' doing the right thing

      This case is easily covered.

      You never can resist the ad hominem, can you.
        You never can resist the ad hominem, can you.

        And you should look up what that term means, because there is no ad hominem in the post to which you refer.

        Nope, "A. D. Hominem" is my real name!
