How is the 'genitive case of Bangla word' a good example? This function's signature contains many hard-coded language specific assumptions.

- Bangla according to the function has only few irregularities, rest is algorithmic transformation of the word given

- Many languages have a huge number of irregularities

- Many languages express case information somewhere else in the sentence-construct, so it's not just a word-transform.

This very much seems to try to replicate the machine-translation efforts of foregone ages.
