Actually, neither way works. The spec says: |
| 14 |
|
| 15 |
Global variables must only contain invariant values |
| 16 |
(see~\ref{sec:metadata-invariance}). If a global variable's value is |
| 17 |
invariant, it may have the value that would be generated at any |
| 18 |
given point in the build sequence. |
| 19 |
|

So you can't rely upon IUSE having the "merged" value in an eclass. |
