I see. Then in part the comparison is showing off exception handling, not FP.

Rust is a good example of functional lang without exceptions (panics aside).

In Rust there are many cases where I could use FP but opt not to because it can make error handling more awkward. For example to collect the result of a map operation to a vector, and if there is an error along the way you want to abort the entire operation. In functional this means collecting to a Result<Vec<T>>. Not sure if I'm just tired today but I can think of how to do it in 5 seconds with a loop. I suspect functional solution would be uglier.
