No, it is a list of the target type, not the source type.

I'm trying to write a generic map function that consumes a list and
emits a transformed list. If I have two lists

a = List<source_type> // full
b = List<target_type> // empty

and a function

target_type fn(source_type)

I should be able to write

a.map(fn, b)

And b[i] should be fn(a[i]) for all i in a's indices.
