Method case_insensitive_tag

  ``int` case_insensitive_tag(`void`|`int` `value`)`

Description

  All tags and containers are matched case insensitively, and argument names are converted to lowercase. Tags added with add_quote_tag() are not affected, though. Switching to case insensitive mode and back won't preserve the case of registered tags and containers.
