Dear Monks,

If I have a set of characters like a-z, how can I match one of those characters followed by another character in the group--but not the same one that matched? For instance, if the group first matches 'd', then the subsequent character should match a character in a-ce-z. I wish I could write:

([a-z] - \1)

In reply to match character in a set, then match one of the other ones by 7stud
