Flow type incorrectly determined to be undefined

[leebyron]

Running eslint with babel-eslint and using flow types:

type SomeNewType = any;

will fail the no-undef lint with 'SomeNewType' is not defined

Appears to be because TypeAlias AST node walks over the id field which is Identifier and eslint mistakes it for an undefined variable usage.

Not sure how exactly to proceed with a fix for this - should babel process out the flow annotations from the AST before passing to eslint?
