Its true for logic programming languages too (e.g. Prolog, Picat, Mercury, etc), so I do not think its to do with line noise languages per say nor a lack of examples (in the case of Prolog). It'll write it but it treats it like Python with funny syntax: not idiomatic. You can ask it to make it more concise or idiomatic but it just can't.
