I don't really like the idea of mixing languages in projects, be it curl or the linux kernel, doesn't matter. If an already established and proven language was already being used for such a long time successfully, that should remain the language of the project. Forks or entirely new / independent projects may be created with whatever new language is being hyped up, and that is totally fine / should be the way to go. In the end, more harm will come from forcing these new languages into long-established projects than benefits.
