I have a ReadStream and I want to detect some substrings in it.

This works, but it is ugly.

((self match:'{|') |
(self match:'|-') |
(self match:'|}') |
(self match:'{{') |
(self match:'}}') |
(self match:'[[') |
(self match:']]') |
(self match:'__') |
(self match:'==') |
(self match:'::') |
(self match:'**') |
(self match:'##') |
(self match:'''') )

Is anybody aware of an elegant approach to this?

Something along the lines of

self matchAny: { '{|' . '|-' . '|}' . '{{' . '}}' . '[[' . ']]' . '__' . '==' . '::' . '**' . '##' . '''' }

thx in advance
