Is it possible to use xgo with go modules? When using the latest version of xgo, it doesn't use the modules, I get an error like

go get: warning: modules disabled by GO111MODULE=auto in GOPATH/src;
	ignoring go.mod;
	see 'go help modules'

IMHO there are two possibilites to solve this: Either add an option to xgo which allows specifying extra evironment variables which are then passed to the container or an extra parameter to enable go modules (which would also pass an environment variable to the container).
