Oh, then the docs in perlfunc are a little confusing.  I read:

               An our declares the listed variables to be valid
               globals within the enclosing block, file, or eval.
               That is, it has the same scoping rules as a "my"
               declaration, but does not create a local variable.

as basically, "it scopes just like a my() variable except you can
refer to it as a fully qualified variable"

Okay, so color me stupid, but why is our()'s lexical scoping
capabilities useful?  Just for 'strict vars' reasons?


PS I just realized I've been using $a in my examples and tests, I
probably should be using something else.
