Making a new language is not the way to do it. A new language means you wipe out all the tools you were using before, from syntax highlighting to libraries to optimizations. Even languages like java, go, julia, lua and D worked on their garbage collection for at least a decade.
Not only that, there is no reason why the math can't be done in a library and used in another language in the first place.
