void EmitBytecode (VmStream & stream)

Appends the bytecode necessary to execute this node. The bytecode machine is a stack-based

machine.

Each ExprNode pushes temporary values it needs to the stack (usually by evaluating

sub-expressions that will leave these values on the stack). It must consume these values and

push exactly one result value on the stack when it is done. This value will be the "result" of

the expression. Even expressions with no results (like a loop) must push a value to the stack

(typically an empty ExprValue()) since the node calling it always expects one value. If the

calling node doesn't want a value, it should "drop" it after running the expression.

After the entire program is executed, the result should be a stack containing exactly one

ExprValue which is the result of evaluation.

void EmitBytecodeExpandRef (VmStream & stream)

Wrapper around EmitBytecode() that automatically expands C++ references to their values.

Used when callers know they want the effective value.

void Print (std::ostream & out, int indent)

Dumps the tree to a stream with the given indent. Used for unit testing and debugging.
