Print "inner". Local symbol should hide the module-scope symbol, 
and "inner" printer is local from where `fun("hi")` is called. 
[The spec 
says](https://dlang.org/spec/function.html#function-overloading) 
that function overloading rules should only apply to functions in 
the same scope.

No idea. What I think it ought to do would be my expectation but 
the fact you posted this as a riddle hints it maybe doesn't work 
like that.
