Installing via homebrew requires manual linking step if Xcodes GUI cask installed

Steps:

1. brew install --cask xcodes to install the GUI app
2. brew install robotsandpencils/made/xcodes to install the CLI

Behaviour:

$ xcodes version
zsh: command not found: xcodes
$ brew link xcodes
Linking /usr/local/Cellar/xcodes/0.17.0... 1 symlinks created.
$ xcodes version
0.17.0

Brew output during install:

$ brew install robotsandpencils/made/xcodes

I assume it's the "skipping link" bit that's the issue, maybe because the formula and the cask have the same name?

Reproduce the installation sequence with brew install --cask xcodes followed by brew install robotsandpencils/made/xcodes, and compare it with the reported brew link xcodes workaround. Inspect the Homebrew formula and cask behavior involved in the install, then verify that xcodes version works without a manual linking step.
