nit

:mod:`symtable`

Oh, I was under the impression that both produce the same sphinx output?

[corona10]

FYI, it generates different output, The latter creates a hyperlink to the module

:mod:`symtable`

So end-user can move to the module more easily :)

Wow, I have been living in a lie! Thanks for pointing this out :)
