Yes, Roger's contribution in the wiki is fantastic as usual. I was especially surprised to see in Roger's construction of the noun k there, how m in amend (m}) was constructed as a table, not a list or a list of boxes. That construction would never have occurred to me as being acceptable because the rank of amend (_ _ _) controls the usage of the x and y arguments, not the m. Is this feature documented in the Dictionary, because I cannot find it?
