My guess — and it’s no more than a guess — is that the documentation is wrong, and should read: Zero or more embedded pattern-match modifiers ...

Even if it is only a guess that the documentation is wrong: if it is underpinned by valid test cases, this warrants a bug report, so this can be evaluated and eventually be fixed.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
