Non-polyfilling version

[jfirebaugh]

I'd like to be able to do const stringFromCodePoint = require('string.fromCodePoint'); and not touch any global state.

Rationale: I'm writing a library. It needs to use the "string from codepoint" algorithm, but it shouldn't go around changing globals itself. For instance, the user may be polyfilling String.fromCodePoint themselves, with another implementation, and my library should not overwrite that.

That’s not what would happen:

String.fromCodePoint/fromcodepoint.js
