Transpiler should error if a static property is declared that the language already defines.

Based on this issue:

Can the transpiler warn you if something like this happens?

Since lib.d.ts is generated from IE definitions, I guess it's entirely possible that the compiler is not even aware there's a name property.

The interesting question is, once it has been added per ES6, how should the compiler handle unwritable properties in general? Would getters/setters be added to interfaces?

@billccn is correct the name declaration is comming from lib.d.ts, and you can edit the file to remove the definition. Also see #1351 for removing these properties from the library file.
