Return type

[Javi]

Hello,

Suppose this pseudo function:
    
    
    proc fn[T](x: openarray[T]): ?
    
    
    Run

Here **x** can be a string, a seq or an array, right?

Is there any way to return a string when **x** is a string, a seq when **x** is 
a seq and an array when **x** is an array?

Thank you.
