3. use strict requires variables to be predeclared before use (among other things) Declare $varAlias with my or our before use and it will compile.
Yeah, it will compile if you declare $varAlias with my, but that's as useful as removing the entire while block. Then the program will compile as well. If you declare $varAlias with my, you get a lexical $varAlias, with no relationship with the glob *varAlias. You want a package variable $varAlias, not a lexical $varAlias.
