Oh no, more programming languages!
There certainly is a practical limit on how many languages a project can take. Maintenance of all of them might prove to be difficult. However, sometimes the usual languages are not enough. For example, GGZ uses the M4 macro language for a lot of its configuration. The Make syntax, which can be considered a partially declarative language, is similarly present in many packages. Some Haskell code exists as a proof of concept Sudoku implementation.

It's the mix which makes it interesting!
