I'm all in for this since this one will help to "normalize" standard library naming (this one is also having "exotic" file name with capital first letter).
I'm surprised by the low usage you found anyways, since rubocop and its style guide recommend English and enforce it by default. Honestly, I'd like all English names to be there by default without having to require anything.
Nice, I didn't know that. Something I don't quite get is, if the functionality of English will be the default (in ruby 2.8, I guess?), what's the point of gemifying it?
