I'm referring to issue 553727 in the tracker. The message you mention applies 
as well. The property.as-path rule is used now to generate subvariant paths 
that correspond to property sets. It does so in a very dump fashion, just 
creating a new path element for each property. So we'll have very funny paths:

.../variant-debug/optimization-off.....

You see, debug is implicit property and "variant-" is not needed. 
Then, <optimization>ofis part of "debug" an should be omitted also.
IOW property.as-path should generate the most compact representation
of the properties given to it.

Hmm... I really don't understand why liberal mind causes any problems? I even 
looked up the word in the dictionary but it still means what I though.

Okay, I'll try to put more effort in it.
