Not in the slightest! jhall isn't a custom language, it loads in pure JS and spits out JSON or YAML. If the node interpreter can run it then it's fair game as far as jhall is concerned. Since Typescript compiles down to CJS you can use its output just fine - although admittedly it would be nicer to be able to run typescript files directly.
