Hi everybody,

It's been already a few times when I wanted to nest an aligned environment in
a multlined environment (from mathtools), itself being nested in an align
environment.  As soon as there are '&' in the aligned environment, LaTeX

  ERROR: Argument of \multlined has an extra }.

Example code:


So far, I've had to resign myself not to use that combination, but I don't see
anything that's fundamentally wrong in wanting it to work this way.

Does anybody have a solution?

To err is human, to purr feline.
