I tend to agree. *Some* functional ideas are welcome in Lua,
for instance I consider defining a map() function and using
it with pure functions (e.g. tostring) idiomatic. Same with
folds.

Going futher and playing with things like composition often
results in confusing and inefficient code.

It can be fun as an experiment though, for instance:
