A left-over from the early days when there wasn't proper exception 
handling. In Squeak 2.x you'll find BlockContext>>ifError: doing, e.g.,

BlockContext>>ifError: errorHandlerBlock
	| lastHandler val activeProcess |
	activeProcess _ Processor activeProcess.
	lastHandler _ activeProcess errorHandler.
	activeProcess errorHandler: [:aString :aReceiver |
		activeProcess errorHandler: lastHandler.
		^ errorHandlerBlock value: aString value: aReceiver].
	val _ self value.
	activeProcess errorHandler: lastHandler.
	^ val
