> case-insensitive key handling in Go’s JSON parser

This was an explicit decision for convenience, because the Go struct fields will be Capitalized to export them but JSON tends to follow a lower case convention.

Just because it’s convenient doesn’t make it a good idea! It’s also not what Go’s other parsers do per the rest of the post.

The "other parsers" in stdlib are gob and encoding/xml.

Gob is a format made for Go, so it does not have a field naming convention mismatch; what's on wire is the Go convention.

encoding/xml isn't really structured as a "convert between equivalent-shaped structs and a message" utility, its struct tags are more like a query language, like a simpler cousin of XPath. Most real-world code using it does things like

    type Person struct {
        FirstName string   `xml:"name>first"`
        LastName  string   `xml:"name>last"`
    }

Where as with JSON there was a clear desire to have

    {"email": "jdoe@example.com", "name": "John Doe"}

parse with as little noise as possible:

    type Person struct {
        Email string
        Name  string
    }

		Again, I understand the rationale. I just don’t think it was a good idea.
