+// 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.
