-If a module with a static name is deployed concurrently to the same scope, there's the potential for one deployment to interfere with the output from the other deployment. For example, if two Bicep files use the same module with the same static name (`examplemodule`) and are targeted to the same resource group, one deployment might show the wrong output. If you're concerned about concurrent deployments to the same scope, give your module a unique name.
