Re: Syntax of 'show babel' commands?

Hello, world!\n

Yes, exactly. In earlier versions, we forbade names that collide with keywords, but that caused compatibility issues when users upgrade to a new version, which may have new keywords that are accidentally the same as user-defined names. We changed that so a used-defined name overrides the keyword, so there is no compatibility problem, but it may lead to a strange behavior like this, as (due to how our parser is written) the name-keyword distinction is done independently of any context.

Perhaps it deserves a warning when parsing the configuration file then? Martin
