strings: copy-on-write
...
Only copy strings when they are mutated. This avoids copying strings in
cases where neither the copy nor the original would be modified during
the lifetime of the copy, e.g. when passing strings by-value.
This is purely an optimization.

Initial commit
...
An assortment of instructions have been implemented so far, mostly basic
stuff such as stack management. The following program can be executed:
int main(void)
{
hello(2);
for (;;) {
system.Peek();
system.Sleep(1);
}
return 0;
}
void hello(int n)
{
int i;
for (i = 0; i < n; i++) {
system.Output("Hello, world! " + string(i));
}
}
