Rust datatypes are not trivial to copy (the way, for example,
JavaScript values can be copied by simply taking one or two machine
words and plunking them somewhere else). Shared boxes require

The fact that arguments are conceptually passed by safe reference does
not mean all arguments are passed by pointer. Composite types like
records and tags *are* passed by pointer, but single-word values, like
records and enums *are* passed by pointer, but single-word values, like
integers and pointers, are simply passed by value. Most of the time,
the programmer does not have to worry about this, as the compiler will
simply pick the most efficient passing style. There is one exception,
