A thought comes to mind...

It strikes me that it would be helpful sometimes to programmatically recognise 
"preview" modules in the std lib. Could we have a recommendation in PEP 8 that 
such modules should have a global variable called PREVIEW, and non-preview 
modules should not, so that the recommended way of telling them apart is with 
hasattr(module, "PREVIEW")?
