What sort of headaches did you have in mind? (Other than the ones

I thought the shell function would inspect the cache variable, and
would set it if it isn't already set. The only difference is that
under my proposal the function would also return a value that depends
on the final setting of the cache variable. So it should be the same
either way, as far as the specialization concept is concerned; it's
only a calling convention.
