Discard the top value on the stack.
@item @code{pick} (0x32) @var{n}: @var{a} @dots{} @var{b} => @var{a} @dots{} @var{b} @var{a}
Duplicate an item from the stack and push it on the top of the stack.
@var{n}, a single byte, indicates the stack item to copy. If @var{n}
is zero, this is the same as @code{dup}; if @var{n} is one, it copies
the item under the top item, etc. If @var{n} exceeds the number of
items on the stack, terminate with an error.
@item @code{rot} (0x33): @var{a} @var{b} @var{c} => @var{c} @var{b} @var{a}
Rotate the top three items on the stack.
@item @code{if_goto} (0x20) @var{offset}: @var{a} @result{}
Pop an integer off the stack; if it is non-zero, branch to the given
offset in the bytecode string. Otherwise, continue to the next
