overview: |
Set Delimiter tags are used to change the tag delimiters for all content
following the tag in the current compilation unit.
The tag's content MUST be any two non-whitespace sequences (separated by
whitespace) EXCEPT an equals sign ('=') followed by the current closing
delimiter.
Set Delimiter tags SHOULD be treated as standalone when appropriate.
tests:
