I accept package/module names as a symbol-list path, and users are
allowed to write them using "display" names, like

\loadModule scholarLY.annotate

Internally I'm converting them to lowercase to prevent ambiguity, so
input is a symbol but with arbitrary case. Having a list of strings
would be much less convenient to use.
