comment Returning all branches of a multiple-valued function
Everything depends on the particular problem you actually are trying to solve. I think the real "killer app" for this kind of task will usually turn out to be Reduce, combined with a formulation that avoids abusing the notation for inverse function in the first place.

comment Most simple example where series expanding a root object actually fails due to branchcuts
It would be easier to answer if you post the Root object that produces the issue in your question. Then we'd be able to see if the message is justified or not.

comment Returning all branches of a multiple-valued function
Mathematically, this is very dubious. Sqrt is defined to be one particular inverse function with a branch cut on the negative real axis. You can define other inverse functions by changing the branch cut, see here, but then they are different functions unless you extend the domain. Therefore, Sqrt[x] + Sqrt[x] == 2 Sqrt[x] is always true. Any parser that violates this will lead to big trouble. It's safer to stick with Reduce if you want multiple roots.

@mfvonh Yes, this option for Heads is another nice thing about Replace.

@ciao In any case it shows that you were reading very carefully. I didn't even notice that point at first.

@ciao Thanks - you're right that the order could be tricky because you have to deal with the lexical rules.
