Nice! But print eval join "+", ("1e", 6) yields 1000000, whereas my aforementioned solution: print sub {eval 'pop(@_)+' x ($#_ + 1) . '0';}->("1e", 6); prints the expected result, 7. Ok, ok, I'm quibbling.

    Ok, ok, I'm quibbling.

    Then add a couple of extra spaces :)

    say eval join' + ','1e',6;

      print eval join' + ','1e',6;

      Bareword found where operator expected at (eval 1) line 1, near "1e" (Missing operator before e?)

      Did this actually test it, or is it because I'm running Perl 5?

      Anyway, print eval join'+0+','1e',6; works okay. Plus, the "+0+" looks nice.

        The point is that '1e' is not a valid number in Perl, so your answer of 7 is at best flawed.

        C:\test>perl -Mstrict -wE"say 0+'1e'" Argument "1e" isn't numeric in addition (+) at -e line 1. 1
