Description Santiago M. Mola (RETIRED) gentoo-dev 2008-06-03 14:54:51 UTC 
Looking at Portage source code, it seems that it supports the following syntax for dependencies:
"myuse? foo/bar"

PMS secion 9.2 specifies use condition groups ("myuse? ( foo/bar )") but not the former syntax.

Either portage should deprecate the old syntax, or PMS should be clarified.

As far as I know, it's deprecated along with ?:.

I don't think it is at all illegal to support a superset of a given specification.

repoman ought to catch that one (same for ?: iirc)...

PMS includes wording about rejecting or warning for invalid inputs in various places. Ideally it'd take the Stroustrup approach and say that for everything...

This is fixed in 2.1.9.
