dmitri's solution returns the line number of the call tothe line in the current subroutine.

blakem's solution returns the line number of the __LINE__ within the current subroutine.

Amended 4:10p PDT I'm not sure why dmitri is building a subroutine reference only to call it. dmitri, do you care to clarify?

At 4:15, after reading blakem's follow-up, I realize blakem is right. dmitri's would be different, if he'd said:

  $linenum = (caller)[2];

but he didn't. So they are equivalent, and I must say that __LINE__ is much simpler.
