Type Casting appears to consistently cause errors

[low-ghost]

I'm using eslint 2.2 and this repo from master. It seems like several rules thow errors due to type casting.

For instance this code:

<any>sinon.stub()

results in this stack trace:

...some removed things.../node_modules/eslint/lib/rules/key-spacing.js:242
            property.key.range[1], property.value.range[0]
                                                 ^

while removing the casting (and jumping through a few typescript hoops) allows the linter to execute and report normal errors. Can give more info if it'd be helpful. Thanks!

on other occasions, different rules have thrown, presumably before this one and due to an underlying problem with the AST.

Type casting is not yet supported by this parser, so this is expected.
