Hi,

I'm just trying to figure out how to create a queue of a specific type in
a .ml file. I can do it in the interpreter as:

>let q = Queue.create()
>Queue.add 1 q 

This creates an int queue.

Declaring this in a .ml file gives 

The type of this expression, '_a Queue.t,
contains type variables that cannot be generalized


I know you can construct a Queue and put an item in it straight away to
specify the type, but I want an empty queue to start with; eg like std::queue<int>
from c++.

Any help appreciated.

Thanks.
