Evaluation of dynamic variables during the initialization phase

[tbarbette]

If one defines something like:

%variables
CPU=[1-8]

%late_variables
THREADS=EXPAND( $(( $CPU + 1 )) )

Then during initialization (creation of files, or %init sections) an error will appear because the evaluation of late_variables has not yet any value for CPU, that will get values defined for each of the runs only.

Solution is to have a dependency graph (ouch) or maybe add a parameter to late_variables to specify that it should not run at initialization phase. Probably easier.

This is generally a bad practice also. Jinja templates generated according to the first variable would be better.
