Possible Ways of Complicating
-----------------------------
* variable scoping: the simplest is to set values in the nearest scope they
can be found in but make `arg` an exception to that, just like in AWK
* variable scoping: lexical scoping is deemed too complex. The simplest is to
look up and set values in the nearest dynamic scope they can be found in,
or globally if not found, and have `arg` create the scopes, which also makes
AWK-style local variables work. A convention of starting locally bound names
with an underscore can keep the global namespace always accessible, and even
overridable if needed.
* reference counting: currently all values are always copied as needed, which
is good enough for all imaginable use cases, simpler and less error-prone
