How to separate module environment from package environment

[gdalle]

An easy approach is to create a shared environment that is different from your default v1.9, for instance pkg> activate @playground, and then pkg> dev your package into it.

How should I use Revise.jl (and other developer tools) to develop a package?

When I create a new package, I often want BenchmarkTools, Revise, and other dependencies that are accessible within my package’s environment, but won’t be added as dependencies for users. I’ve tried playing around with [extras], but I have not been able to replicate this usage. How are folks using Revise when developing a package? Are you adding Revise as a dependency, then removing it before you commit?
