I am a parse tree leaf representing a selector.

	inappropriate
	emitForEffect:on: emitForValue:on: sizeForEffect: sizeForValue:

	printing
	printOn:indent:

	testing
	isPvtSelector

	code generation	top
	emit:args:on:
	emit:args:on:super:
	size:args:super:

	inappropriate	top
	emitForEffect:on:
	emitForValue:on:
	sizeForEffect:
	sizeForValue:

	printing	top
	printOn:indent: If control gets here, avoid recursion loop.

	testing	top
	isPvtSelector Answer if this selector node is a private message selector.
