If you just want a text substitution utility, then this is proof that you can implement that by using sed in a controlled manner. Why bemoan something for doing more things than you need it to right now? This is what general-purpose computing is all about.

I do like the thought experiment that I might not want Turing completeness from a language in a specific use case.
