#X text 64 52 Calls a user-defined operation for each of the incoming
list's items and returns a list of the return values.;
#X text 64 90 [list-map] is a helper abstraction to make element-wise
operations on lists easy to patch. The basic idea is to bundle a list-serializer
and a list-repacker into one object. Then you connect whatever operation
should be applied on every list item to the right outlet and send the
modified items back to the right inlet. Here the modified elements
get packed into a list again and sent to the left outlet of [list-map].
