 	VecArray		Implement array using vec()
 	SubstrArray		Implement array using substr()
 	VirtualArray		Implement array using a file
 	ShiftSplice		Defines shift et al in terms of splice method
 
-Bugs
-	Make yyparse recursion longjmp() proof.
-	Make "delete $array{$key} while ($key) = each %array" safe
-	Wrong line reported for runtime elsif condition error
-	TOOSTRICT is not too strict
-	recv and sysread should taint
-
-Regexp extensions
-	/m  for multiline
-	/\Afoo/ (beginning of string, or where previous g match left off)
-	/foo\Z/ (end of string only)
-	negative regexp assertions?
-	/<>/x for grouping?
-	/f for fixed variable interpolation?
-	Rewrite regexp parser for better integrated optimization
