Obtain a map representing the composition of userops from all the given libraries

<p>
Name collisions are not allowed. If any two libraries export the same symbol, even if the
definitions happen to do the same thing, it is an error.

@param <T> the type of values processed by the libraries
@param libraries the libraries whose userops to collect
@return the resulting map
