OK. Let's say I'm implementing HugeOnDiskArray, and instead of slurping
the array in and grepping over it, I want to grab the elements one at a
time, run them through the grep function's coderef, and stick them in
another HugeOnDiskArray. Or, if I have RemoteArray (which works with an
array on another computer via a server and a TCP/IP connection), I might
want to try to serialize the code reference given to grep and run the
grep on the remote computer. (If I can't serialize the coderef due to,
say, nonsense with closures, I'd run the grep locally.)
No, "it won't work efficiently" isn't the same as "it won't work", but I
suspect there are cases I haven't thought of.
