"Dep does not support using multiple major versions of a program in a single build. This alone is a complete showstopper. Go is meant for large-scale work, and in a large-scale program different parts will inevitably need different versions of some isolated dependency."

Russ has asserted this from day one, and has brought several examples out in evidence, but has simply not convinced the committee that it’s true. Calling it a serious problem, let alone a showstopper, is a significant overstatement. The strongest claim that can be made on this point is that it’s a matter of opinion.

OK that's enough for me. "BDFL" clearly correct, random critics totally unwilling to consider the proposition. More language developers are realizing that hierarchical imports with directory name conventions are a good practical thing that just works. Multiple versions come for free with this arrangement. If your tool can't handle that, your tool sucks.
