I thought about it however there is a problem. When you have a
gettable stream, you don't always know how much elements remain in the
stream. You are then obliged to read all elements before you know if
there was enough or not.

This is a problem because once read, the elements may not be available
anymore. So, if the method signal an error, all elements that have
been read are lost.
