Hi,
I prefer a solution where the end token is changed rather than
the content. Look at the embedded parser construction in
MoinMoin syntax for an example.
I instead propose to introduce an instruction to the parser in
the start-tag to expect a different end token. Something like:
{{foo #endtag:foobar}}
content
{{/foo}}
still content
{{/foobar}}
For verbatim we could use the same technique as MoinMoin, either:
{{{{
content
}}}
more content
}}}}
or:
{{{arbitrarystringofalphanumerics
content
}}}
more content
arbitrarystringofalphanumerics}}}
Best regards,
Andreas Jonsson
