==Example==
{{tlx|If in category|Amastra subsoror|Extinct gastropods|Dead as the dodo|Perhaps it's still alive}} produces {{If in category|Amastra subsoror|Extinct gastropods|Dead as the dodo|Perhaps it's still alive}}.

==Limitations==
This template is very expensive.

Only detects categories directly on a page, not those added indirectly through templates.
