I also mostly agree with it for base OCaml (and I write OCaml every day), but it's worth noting a lot of the complaints--even the ones outside of the 'standard library' section--can be fixed by using a better standard library. (Like Jane Street's Core/Async, which is what I'm most familiar with.)

I do disagree with several of those complaints though (not auto-converting between numeric types is a feature, not a bug!), and several of them are the kind of things that seemed like a big deal when I first started using OCaml and now no longer do. (Like the record field names issue...if you're writing well-organized code each type almost always has its own module anyway, so this doesn't matter much.)
