Warning: `using A: B` will only be allowed for single bindings


On Julia 0.7-alpha I get this warning:

Warning: using A: B will only be allowed for single bindings, not modules. Use using A.B instead

import CmdStan: CmdStan, CMDSTAN_HOME, Diagnose, Optimize, Sample, Stanmodel, Variational, set_cmdstan_home!

works fine. Is there a reason for this?

What I’m really trying to do is reexport all symbols of CmdStan except one, which I want to extend (my idea of “stacked environments” :slight_smile: and export the updated method
( https://github.com/goedman/StanStackedEnvironmentTest.jl ).

But maybe this is a bad idea and should use multiple dispatch for that?
