I strongly hesitated saying anything at all b/c there are so very many different rules governing the behavior of every single kind of symbol. Though one jumping off point is the use of the parenthesis, without slashes prior to them and them meaning alternatives within a grouping context rather than merely “remembering”, for the sake of e.g. replacement or copying, so e.g. in the Unix CLI “grep” command this would not work even with the -e parameter (I am not so sure about perl-style though, or rather, this would work within pure perl, but perl-style regexps from within grep is another matter, plus that option itself is not universal across all forms of Unix).
In any case, I hoped that the YoMama joke would be universally understood and appreciated regardless, across all of the many & varied language barriers 😜.
