Although I looked up $= in perlvar, I can't make heads nor tails of it! I read $= is assigned () is assigned <> with the assignments being right-associative. But that doesn't make sence, and even if it did, just printing the value of the assignment is normally no different from just printing the rhs, so what's the point?

Baffled,
