There's nothing that defines a "mini language" as such. It's about as meaningful a term as "scripting language".
And as far as that's concerned, regular expressions indubitably are a language unto themselves. While it isn't practical in any sense of the word to do so, you can model arbitrarily complex control flow with them (though you need Perl's extensions to the language to model loops).
Makeshifts last the longest.
