[O] feature request: re-compute cache without evaluation

[Henning Redestig]

Hi,

I write many source blocks that take a fairly long time to execute
(several minutes). Sometimes I find myself wanting to do cosmetic
changes to the code, that I know (for sure) do not change the output,
after the first evaluation. Unfortunately, after having made these
changes the cache obviously does not match the code anymore and I have
to re-evaluate to update the cache. I know it goes against the strict
'reproducible research' idea but still I would like to be able to
re-compute the cache without actually evaluating the block as it is
not efficient to re-evaluate for the sole purpose of updating the
cache.

What do you think?
