demo's workaround for nested loop accessing

- While this is a legit bug this workaround will always allow access and
also can not create conflicts of named variables in nested contexts so
is actually safer, regardless of bug.

- Does not require aliasing (creating new namespaces) in nested loops.
Like everything else in Mañana you can always access things by starting
at the top namespace (i.e.: "root", "$window", or "$manana")
