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. If more than one value is listed, the list must be placed in parentheses. The our declaration has no semantic effect unless "use strict vars" is in effect, in which case it lets you use the declared global variable without qualifying it with a package name. (But only within the lexical scope of the our declaration. In this it differs from "use vars", which is package scoped.)
