Thanks. This is very helpful. I remain puzzled by this: u // FullForm FullForm[Symbol["u"]] FullForm[Unevaluated[Symbol["u"]] Head[u] FullForm[{1, 2, 3}] Head[{1, 2, 3}] In other words, Head and FullForm seem consist for the list, and inconsistent for the variable u. u's full form is just, literally "u", not Symbol["u"]. But the list's FullForm starts with "List". Head of Symbol["u"] is not Symbol, but "u". What gives?
