Just tried it:

| $ rpm --define 'foo bar' --eval '%foo' --define 'foo baz' --eval '%foo' --undefine 'foo' --eval '%foo'
| bar
| baz
| bar

Very nice, very nice. I cannot just wait until I see Jeff's commit
to support this:

| $ rpm --define 'foo foo' --define 'foo bar' --define 'foo quux' --eval "%{@foo:\n}"
| foo
| bar
| quux

Very interesting what rather cool functionalities are under the hat
of RPM and which nobody beside Jeff seems to know about at all. I
guess there are even more those cool things which we just have to
discovered... ;-)
