Non-standard variable name
Say I want to represent HTTP headers with a struct, something like:
Headers struct
'x-requested-by' 'foo'
it definitely does not like a variable name with hyphens, etc. Any way around this?

Specify actual header names as field tags and use those field tags when encoding or decoding the struct to the wire.

@ThunderCat can you show an example of that? will upvote thx

Or you could use amap[string]stringwhich is whathttp.Headeris in the standard library.

Using a struct for headers is going to be pretty rough anyway. The set of headers you can handle will be fixed at compile-time, you'll be allocating for headers whether or not they're present, and you won't be able to iterate them. I would strongly recommend just using a map like the stdlib (and every other HTTP lib I've ever seen) does.

Specify actual header names as field tags and use those field tags when encoding or decoding the struct to the wire. See the encoding/json package for an example of how to do this.
If the higher-level problem is storing key-value pairs with arbitrary string keys, then use a map.
