There's also: |

|
| 11 |
Global variables must only contain invariant values |
| 12 |
(see~\ref{sec:metadata-invariance}). If a global variable's value is |
| 13 |
invariant, it may have the value that would be generated at any |
| 14 |
given point in the build sequence. |
| 15 |
|
| 16 |
which is true for all global variables, not just for metadata ones. |
| 17 |
That paragraph's there because historically global variables have done |
| 18 |
various different things (being re-evaluated for every phase, or just |
| 19 |
some phases, or never, or when loaded from VDB, or ...). |
