Notes:
	The additional scope in 'for' is to safely encapsulate pre-branch, as variables can be declared here.
	do-while's 'end' is only there for the break/continue keywords.
	break and continue will also unwind scopes, up to the innermost control-flow level.

break/continue within nested scopes:
	Because control flows can be nested, a stack of scope depths may be needed for break/continue...
	However, this would get more complicated with closures.
	To fix this, scopes may need to remember their own depth, and the depth of the innermost control-flow level.
	If a scope's depth is 10 and the inner control-flow-level is 7, then calling break/continue will jump AND unwind to the inner control-flow level.

JUMP word:
	opcode
	type (absolute, relative)
	conditional (always, if_true, if_false)
	-

	value

absolute:
	"value" is relative to the code sections starting position

relative:
	"value" is relative to the program counter, after this opcode has been read from the bytecode

always:
	Always jump

if_true:
	pop the stack top
	if the popped value is true, then jump
	else ignore

if_false:
	pop the stack top
	if the popped value is true, then ignore
	else jump
