What did you do?

What did you see happen?

The expected string replacement didn't happen. However, when a garbage $ variable was used the replacement did happen.

What did you expect to see?

I expected string replacements to happen, as documented.

This looks like it's working as intended.

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.
