|
|
|
|
Merges the specified observable sequences into one observable

observable sequence produces an element. The observables can be

|
passed either as seperate arguments or as a list.

Examples:
|

>>> op = with_latest_from(obs1)

>>> op = with_latest_from(obs1, obs2, obs3)

Returns:

An observable sequence containing the result of combining

elements of the sources into a tuple.
