Leverage substring for BCP335 for module deployment names

[johnthcall]

When I compile a bicep file like the following it rightfully gives BCP335: The provided value can have a length as large as 77 and may be too long to assign to a target with a configured maximum length of 64.

@minLength(1)
@maxLength(63)
param parameter string

module MyModule 'Modules/MyModule.bicep' = {
  name: '${parameter}-${uniqueString(deployment().name)}'
  scope: resourceGroup('mySubId', 'myRg)
  params: {
  }
}

I have tried adding
var myModuleDeploymentName = '${parameter}-${uniqueString(deployment().name)}'
and changing name to the following but I still get the same warning as it appears substring is not determining that the max length of the substring is 64.
name: substring(myModuleDeploymentName, 0, min(length(myModuleDeploymentName), 64))

@johnthcall this looks like a bug, so I think it's fair to raise an issue for it - we don't tend to triage discussion topics.

By the way, as of Bicep 0.34.1, module names are optional (see https://github.com/Azure/bicep/releases/tag/v0.34.1)

Raised #16816 for this. Am I correct in remembering that the name of the module becomes the deployment name? If so, we would like to continue providing a name for the deployment
