In the example, freeing the arena is safely delayed until printing. All operations are also zero-cost abstractions
over performant implementations at the core of the standard library. Code blocks are identified by indentation. Furthermore:
def functions that can fail and produce new values.
service functions run safely; if a def fails, resources are cleaned up.
new declares a new type variation.
@mut denotes mutable variables (their values change as the program runs).
@on is automatically added as first argument - here to store string addition on a fast arena allocator.
@all iteratively applies a function to reduce a bunch of expression outcomes to one value.
. member values or curries a first argument into functions.
