    A number of Perl's "features" are actually bugs that were discovered, found to be useful and have been documented and carefully preserved. One that springs to mind is that s/.../.../ee evaluates twice, s/.../.../eee evaluates thrice, etc.

    I have a feeling that the baby cart is one of these.
