Thank you for the correction. Is it possible to use NSE in say Python or JavaScript?

Yes, though the languages do not support it explicitly you can simulate lazy evaluation by wrapping all your arguments in closures. This way they won't be evaluated until called within the function body.

Sidenote, the evaluation model of python can be surprising. List comprehension will create implicit function scopes that can trip you up.
