Your general point is a good one but I don't think irregular verbs are the best example of error correcting redundancy, or evolved shortcutting. In most cases they are just a relic of genealogy, and don't serve those purposes:

> Most English irregular verbs are native, derived from verbs that existed in Old English. Nearly all verbs that have been borrowed into the language at a later stage have defaulted to the regular conjugation.
