I know that Jim already opened the door by saying he would accept the
feature if it were written.  For my part I see this as creeping
featurism and would vote against it.  With the "camel in the tent"
parable in mind I expect sleep to inevitably include full human date
parsing routines at some point.  If it will accept "1d -5s" then why
not "all night" or "until the next blue moon"?
