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 (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.

etl – Expandable token list operations

This package provides expandable token list operations for which expl3’s l3tl only has unexpandable variants. These expandable versions are typically slower than the unexpandable code. Unlike the l3tl versions, the functions in this module may contain braces and macro parameter tokens in their arguments, but as a drawback they cannot distinguish some tokens and do not consider the character code of group-begin and group-end tokens.

Additionally a general map to token lists is provided, modelled after the expl3 internal __tl_act:NNNn but with additional features.

The package has no immediate use for document authors; it only contains expl3 functions intended for programmers.
