Re^3: Search and Replace Within Subscopes

You can use any pair of non-alphanumeric, non-whitespace charaters as delimiters of a regex pattern. So these regexes are equivalent:

s/a/b/;
s"a"b";
s^a^b^;
s{a}{b};
s(a)[b];

Only ' is an exception, this character prevents variable interpolation if used as delimiter

Advantage is that you can use / inside them without escaping the character. Also it could be argued that {} [] or () as delimiters just look better, especially for complex patterns. Edit: Deleted one erraneous example found by ikegami
