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

Thanks, that got the basic proof of concept working. Now the issue is,
I want to write a generic map function whose output type should not
need to be encoded in the Enumerable type.

Note also that this dies in a different place in 0.92 (last tagged
release before the "generic delegates support" feature):
$ valac --pkg gee-1.0 test.vala
test.vala:23.37-23.37: error: Argument 1: Cannot convert from `G' to `int'
a.map( (i) => { return "%d".printf(i); }, b);
What do I need to do to get the following code to compile? It dies with
$ valac --pkg gee-1.0 test.vala
