Outermost Strategy.

---------- Loop: ----------

isPalListKind -> U91(isPalListKind) with rule isPalListKind -> U91(isPalListKind) at position [] and matcher [ ]

Now an instance of the first term with Matcher [ ] occurs in the last term at position [0].

Context: U91([])

We used [THIEMANN_LOOPS_UNDER_STRATEGIES] to show that this Loop is an Outermost-Loop.
