// Package httpm has shorter names for HTTP method constants.
//
// Some background: originally Go didn't have http.MethodGet, http.MethodPost
// and life was good and people just wrote readable "GET" and "POST". But then
// in a moment of weakness Brad and others maintaining net/http caved and let
// the http.MethodFoo constants be added and code's been less readable since.
// Now the substance of the method name is hidden away at the end after
// "http.Method" and they all blend together and it's hard to read code using
// them.
//
// This package is a compromise. It provides constants, but shorter and closer
// to how it used to look. It does violate Go style
// (https://github.com/golang/go/wiki/CodeReviewComments#mixed-caps) that says
// constants shouldn't be SCREAM_CASE. But this isn't INT_MAX; it's GET and
// POST, which are already defined as all caps.
//
// It would be tempting to make these constants be typed but then they wouldn't
// be assignable to things in net/http that just want string. Oh well.
