Yep, PERL for instance has named blocks and you can use constructs like
	next [BLOCK_NAME]		( continue in C )
	last [BLOCK_NAME]		( break in C )
and, I'm not quite sure about this one since I've never used it,
	redo [BLOCK_NAME]

BLOCK_NAME is optional and if omited the statement applies to the current 
block.

Personally, I like this implementation a great deal
