## Detailed Description

template<typename T>
struct xpress::is_stream< T >

Check whether type `T` is a stream.

A stream has a begin and an end, as well as a typedef `value_type`. A function taking a stream as argument will iterate this stream at most once (this is not something that can be asserted by type checking).
