Dynamic-place module-predifined? requirement

[Nathaniel W Griswold]

Hello. The docs at https://docs.racket-lang.org/reference/places.html?q=places#(def._((lib._racket%2Fplace..rkt)._dynamic-place)) state:

"The module-path argument must not be a module path of the form (quote sym) unless the module is predefined (see module-predefined?).”

Is this true? I noticed if i use a ‘<module-name> symbol it does in fact load my module for the place. I have been making separate modules to include with a path name because of this line in the docs and was wondering if that’s really necessary. What modules are predefined and what does this requirement mean?

Thanks

Nate
