in thread return file descriptor from function

Although the question was terse, I think that is what the OP most probably meant. And yes, using a lexical filehandle enables you to use it almost as any scalar variable: to pass it to a function, to return it from a function, to take a reference to it, to store it in an array of filehandles or in a hash, to make it a local persistent object in a closure, etc., even if you don't know or don't want to know anything on typeglobs.
