I don’t get what you’re about. The root comment clearly presents a structure of a separate type. The fact that it happens to contain a single string field is completely irrelevant (what type an actual username should be, a float?). “Stringly typed” is about stringifying non-string values to save typing work and is not applicable here in the slightest.
I wasn't replying to the root comment, I was replying in the context of the subsequent three comments, specifically:
> > > Crazy that actually using your type system leads to better code.

> I don't think a reasonable person would consider storing a username in a string to be "stringly typed".
#1 was saying that the root comment shows better code using the type system.
#2 was clearly referring to the case where you don't do this as being an anti-pattern.
#3 is saying that storing a username in a string, without wrapping defining a distinct type for it, was not stringly typed. But as I pointed out, it certainly is.
If you doubt my interpretation of #3, the same commenter said this in another comment: "Is it really more 'programmer friendly' to create wrapper types for individual strings all over your codebase?"
