Macrodef very explicitly says that the macro invocation is treated as a
Task.
Unfortunately, I need macros to simplify gathering resources, so macrodef
doesn't help me.
So I'm requesting <resource-macrodef> and <resource-macro> -- just working
names, I'm sure something better exists -- which are isomorphic with
Macrodef but have invocations that are typed as Resource Collections.
Syntax could be almost identical, but use <union> in place of <sequential>
as the body element.
Or, perhaps better, just modify macrodef so it recognizes when its body is
a union rather than a squential and changes its type (and the type of its
invocation) appropriately.
(Personally, I really wish that you'd left macros as pure syntactic
operations rather than constraining them to be tasks in the first place...
but since that decision was made, I think you need to "drop the other
shoe" and give us the resources equivalent.)
