They can but the compiler will just tell you it's ambiguous and to qualify it. Also bear in mind Nim has very strong static typing, so for things to clash they also have to have exactly the same type, otherwise no worries.

You can even rename symbols on import or force qualification for all symbols, but I've never needed to do either in years of heavily using the language.
