Almost, Moandji. This would be the syntax you're looking for in this
particular example:
List<String> userNames = userList.map(#(User u) (u.getName()));
Or, alternatively (both are legit):
List<String> userNames = userList.map(#(User u) {
return u.getName();
});
If I put them in a bad light, I apologize - that wasn't my intent. My
intent was to simply state the proposal, and inject a little despair
into the crazy syntax for function -types-. The syntax for the
closures themselves is fine, and, in fact, one of the few that really
works well with existing java style guides (braces imply newlines,
etc).
