maps with int keys

[skaldesh]

Hey, I was wondering, why does the code generator ignore my map in this struct?

type Test struct {
    M map[int]int `msgp:"m"`
}

As far as I know, the message pack spec allows such keys for maps

[philhofer]

You're right that the spec allows for such keys. (Actually, last time I looked at the spec, it allows even nonsensical objects like arrays and float64 NaNs to be map keys...) Presently, the code only implements "string-like" keys, as that preserves transparent JSON interoperability; there's a caveat to this effect in the README. This is something I'd consider fixing for a v2 revision, but probably not as part of v1.

Any update?
