Subject Re: [ASJS] Adjusting FalconJS output (no general discussion in this thread, please)

The Closure Builder is perfectly capable of resolving/optimising
namespaces, especially when provided with the proper context using the
'goog.require' statements and '@type' annotations. I don't think there
is any reason to duplicate this information in a custom solution.

As to 'collisions' with reserved objects, the Closure Compiler is well
aware of those: I just create a package 'alert.acme.flex.SomeClass'
and tried to feed it through CC and I got: "ERROR - Variable alert
first declared in externs.zip//window.js". These 'externs' definitions
are part of the Closure Tools, so I think we're safe in this regard.
