+
+This provides expandable token list operations which are only implemented
+unexpandably inside of `expl3`'s `l3tl` module. While being expandable these
+operations are typically slower than the unexpandable alternatives. Also there
+are tokens which are not expandably distinguishable in TeX (those are active
+characters which are let to the same character with a different category code).
+
+Additionally a general map to token lists is provided modelled after
+`\__tl_act:NNNn` with additional features.
