i think i have it, my fault basically, its due to me having several versions of go, on-the-go;
when go get 'install', compilation of the package was done by go1.6.2, hence the slow down when i split code off into a package. when i used type aliasing, go build used a cached compiled package that was done with go1.9. (haven't actually confirmed this, but it all fits.) -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
