 Returns a list of unique values from the invocant/argument list, such
 that only the first occurrence of each duplicated value remains in the
-result list. The order of the original list is preserved even as
+result list. C<uniq> uses C<< &infix:<===> >> semantics to compare whether
+two objects are the same. The order of the original list is preserved even as
 duplicates are removed.
 
     say <a a b b b c c>.uniq    # a b c
     say <a b b c c b a>.uniq    # a b c
 
-By default, C<uniq> uses C<< &infix:<===> >> semantics to compare
-whether two objects are the same. Use the C< :with > parameter to
-override this default.

-    say <fly you fools>.uniq(:with({ $^a.chars == $^b.chars }))
-    # fly fools

 (Use C<squish> instead if you know the input is sorted such that identical
 objects are adjacent.)

 Returns a list of values from the invocant/argument list where runs
 of more than one value are replaced with only the first instance.
-Unlike C<uniq>, this function only removes adjacent duplicates; identical
-values further apart are still kept. The order of the original list is
