  filter($sequence,$function) => head()

This seems nice, however it will probably filter the whole sequence and
only then take the head() of the resulting sequence.

Is there any guarantee that the evaluation of filter() will stop as soon as
an initial item is produced?

Thinking about this a little more,

what I mostly want is first-available($sequence,$function)

and you get back the first member of $sequence where $function is true.

Which is equivalent to

filter($sequence,$function) => head()

So I need to stop using ($a,$b,$c,$default)[1] so much and start using
