go compiler doesn't catch some errors

[arp242]

For example:

:!go install  zgo.at/goatcounter/cmd/goatcounter ./cmd/goatcounter/ 2>&1| tee /tmp/vsJ7OHh/29
build zgo.at/goatcounter/cmd/goatcounter: cannot load zgo.at/goatcounter/stripe: module zgo.at/goatcounter/stripe: Get https://proxy.golang.org/zgo.at/goatcounter/stripe/@v/list: dial tcp: lookup proxy.golang.org: Temporary failure in name resolution

Another one I've run in to a few times is a module without go.mod:

$ go build
# _/home/martin/n
runtime.main_main·f: function main is undeclared in the main package

# a
runtime.main_main·f: function main is undeclared in the main package
