It was written at 3am as I was falling asleep on my keyboard...

I am french born and raised, btw.

I think you give too much credit to native speakers of any language.

A bit ironic, no? That such a thing, almost exclusively useful for French people, has to come from a non-native speaker. And that the only obviously French comment so far is a critique about the style...

We sure do know how to complain. :)

(slightly unfair, of course---obviously the complaint about grammar had to come from a native speaker; who else would notice it in the first place..?)

The irony of course being that I thought to myself as I was reading it "that's some mighty easy-to-understand French". A long time ago I used to visit francophone Africans in a UK asylum centre who were always notably easier to understand than the French.

There's a PR for that ;) https://github.com/steeve/france.code-civil/pull/1/files

Oh no, this kind of grammatical errors show that it's clearly a native French speaker. We French suck at our own language - partly because it is fairly complicated, and partly because people don't bother learning.
