in reply to Small question: Why can't I print "@-"?

If your code executes print "@-"; and the output is @-, then your perl is probaby version 5.005_03 or older. @- and @+ aren't supported until perl version 5.6, if I remember correctly.


Updated: Interpolation of @- and @+ seems to be broken until version 5.008.

    No, I still see "@-", perl version = 5.6.1.

      You're right, my mistake. I tested with perl 5.8 and 5.00503, but not 5.6 or 5.6.1. Evidently 5.8 recognizes @- as an array without disambiguation via @{-} where versions up to at least 5.6.1 do not.
