Description

When creating a short alias for some.really.long.name.Foo the alias should almost certainly be Foo. If someone writes

goog.scope(function() {
var Bar = some.really.long.name.Foo;
});

it is surprising and a violation of the style guide. We could probably warn for this pretty easily in the ScopedAliases pass

Contributor guide

Research direction
Examine the ScopedAliases pass (ScopedAliases.java) and add logic to compare the alias variable name with the last part of the fully qualified name, emitting a warning when they do not match.
