Roughly yes.
Rather than think about it from Haskell-Monad-semantics, consider thinking about it from the F# spec of syntax translation:
Depending on which methods you support on the builder, certain syntax forms will either 'light up' and work, or else be compile errors.

Hi,
If I'm implementing the 'Zero()' method in a workflow builder class, should it create what is effectively an 'mzero' value from MonadPlus?
For example, if I do a workflow for 'Option<'X>', then Zero() results in a value of 'None'; in a workflow for 'List<'X'>', Zero() results in a value of '[]'.
Presumably if the workflow doesn't have MonadPlus semantics, then I would have to omit 'Zero()', right?
Hence no unbalanced if-statements allowed in my workflow expressions if that's the case.
So as an another example, if I was doing a state transformer workflow, would that fall into the second category?
Your advice, please...
