Oh, right, I'd forgotten about that option - that would work.=0A=
=0A=
There's still the question of what it would do without a predicate.=0A=
Making the predicate mandatory in the initial proposal would help avoid the=
 confusion of whether `first() should behave like array_filter() and any() =
and filter for the first truthy value.=0A=
=0A=
Calling it [iterable_]search_callback() or first_matching() or find() might=
 help distinguish this from the reset()/end()/next()/prev() family of funct=
ions - not happy with any of my naming ideas=0A=
=0A=
Thanks,=0A=
