`INTERNAL_COMPILER_ERROR` while trying to build custom changes to Chrome.

I know the source is riddled with syntax errors, but didn't expect to crash the compiler.

[languages.js as a GIF](https://cloud.githubusercontent.com/assets/1449368/10128054/dac9c2a4-6561-11e5-96bc-6217596c6a38.gif)... it's really ASCII, but GitHub failed to upload it as `.js` or even `.txt`.

I think it's related to the "funciton" typo.
