We cannot use @ because it's a legal character in flag names.

My feeling is that our present rules for IUSE_EFFECTIVE and
IUSE_REFERENCEABLE are already complicated enough. The package
manager should treat runtime switchable flags as normal USE flags,
except when deciding if a package should be rebuilt.

What we add on top of this as tree policy (repoman etc.) is another
issue.
