# A guided tour of Berry (Python-like) running on calog.
# Demonstrates: a def function, a list built and iterated with a for loop, a map
# iterated over its keys, then the jsonStringify and cryptoUuid natives.
# Run: bin/calog examples/scripts/languages/berry.be

# A function.

# Iterate the list, accumulating a sum.

# list.concat joins the elements into a readable string.
