>From http://www.digitalmars.com/d/2.0/template-mixin.html: "The declarations in
a mixin are ‘imported’ into the surrounding scope. If the name of a declaration
in a mixin is the same as a declaration in the surrounding scope, the
surrounding declaration overrides the mixin one." In other words, declarations
in the current scope always hide declarations in the mixin.
