No, I think it will take the first parse, because when the next element can
match either an element particle or a wildcard, the element particle will be
chosen.

Then I suggest you make the suggestion as a comment on the last call spec
which has just been published.

I can't say I feel strongly about it. Which way is easier for implementors
will depend, as always, on the internal design of the implementation (and in
particular on how counters are implemented). I can see it being tricky to
formalize the notion of "the particle that is currently gobbling up input" -
or perhaps not, it might simply be a case of saying that in the event of an
element matching more than one particle, the preferred one is the particle
to which the previous element was attributed.
