I have used the Angular one and the Laravel one, and both are a chore to use, because they interrupt your flow. If I'm writing the view of my component, I don't want to have to switch to another file, think of a key that identifies that text well enough and then translate the text, thinking of potential plurals and others. I just want to write my damn text.
I'd rather spend days doing the mind-numbing work when needed rather than slow down my development process and remove all enjoyment from it ad vitam aeternam because of i18n-ing on the fly.
