NAME
        block - Block statements in LPC.


DESCRIPTION
	A block is a special statement, that begins with '{', contains a list
	of statements, and ends with '}'. The block may also define
	local variables.


NOTE
	Currently, the local variables are visible until the end of the
	function. This will be fixed later (any year :-).
