*	parser: prohibit redefinitions of symbols and verify existance on use	Patrick McHardy	2014-02-04	1	-0/+6
	This patch fixes some incorrect behaviour of symbolic variables: - prohibit redefining an existing symbol - verify existance of a symbolic variable during parsing instead of evaluation The second point makes sure we don't allow recursive definitions (var = $var), which lead to a crash due to stack exhaustion.
