Uhm... Hardly applicable in my case. :( I'm  trying to "mask" the
heterogeneous nature of our cluster to the users (having 7 partitions,
one for each set of homogeneous nodes and a default $SLURM_PARTITION
that includes 'em all). The only thing they have to select is if the job
is "normal" (24h, high prio), "debug" (15', medium prio) or "long" (72h,
lowest prio).

Yup. I's nearly what I did till now, but it keeps complaining about
missing parenthesis (that I triple-checked are balanced!) or other weird
issues.
Moreover, the only way to test is on the production cluster... Not great :(
And some construct seems not to work (like ipairs() ).

That would be really useful!
