Ah, I see. Yes, it would not make sense to do this for Go. >> A package can be installable by itself, sure. > > Would that then be in the form of an object, or would you make an > archive out of it? It could be either way.

It's normal to have a single package which had conditionally included source files. But what you are describing seems to be the case of the same source file going into two different packages. I don't know why that would ever be useful or interesting. But, yes, it could be done, if both of the two different packages used the same name at the source code level. Ian
