Hi Ben,
I agree that it reduces its applicability, but I see that as a virtue. Filter
and Map are useful despite being less applicable than Reduce, since
might fail on nil anyway. Or maybe a with/1 pipeline might work better
than the pipe operator if you want a succession of happy-path matches?
If we move forward, it might be better to explicitly declare the returned

All,
I wrote a macro which allows for using a pattern to essentially extract a
value from a data structure:
@doc """
Filter a value out of data using a pattern with one variable. Returns a
default value
if no match. Raises if pattern contains no variables or more than one
variable.
