Sorry, I've checked further. The problem is actually having a directory called main. I had naively assumed that with one package per directory, one should call the directory the same name as the package it contains. Apparently, this does not work for package main. (So what minux says is correct, but there is still a problem; I have updated the original post).

What are the "bad effects"?

1. When I try go test main I get: /tmp/go-build550118144/main/_test/_testmain.go:9: cannot import "main" and FAIL main [build failed]
2. When I try godoc main (1) godoc treats main as a command not a package and (2) godoc does not document my funcs and vars (even if they are Public).

See https://groups.google.com/forum/#!topic/golang-nuts/ubYw0OQXLvA

The problem is that the test driver (_testmain.go) needs to import the
package and if the import path is "main", gc will refuse to import it.

The reason is simple, the packages in Go program must have unique import
paths, but as the main package must have the import path "main", you can't
import another "main" package.

This is working as intended.

ok, but this should be documented so other newbies do not make the same
mistake.

Martin
