This would be a great feature. @diegohaz Any chance getting this merged?

[dennisreimann]

Can you provide feedback on this, @diegohaz? Anything I can do to get this merged? Otherwise I'd close this PR.

I'm sorry for not showing up, guys. I've been very busy.

I'm still worried about the unnecessary weight it would add to the users' bundle since strings are not minified.

But, people seem to want this, so I guess we should merge it. Maybe we should just add a note on README warning about it?
