Multitarget assignment does not infer types of cast expressions

[Chuck]

This program should work, but gives two errors:

class X
	def main
		a = 'aoeu' to Object
		b = 5 to Object
		x, y = a to String, b to int
		assert x.length == 4
		assert y * 2 == 10

The errors:

(6): error: Cannot find a definition for "length" in "x" whose type is "Object".
(7): error: Cannot apply STAR to Object and int. Try finding a method that performs this function.

It seems that x and y are inferred as Object instead of the types that the right hand expressions are cast to.

Due to type erasure/obscuration from passing through a List.
same as

class X
	def main
		a = 'aoeu' to Object
		b = 5 to Object
		l = [a to String, b to int]
		x = l[0]
		y = l[1]
		assert x.length == 4
		assert y * 2 == 10

patch coming...
Should the above list case also be a bug ?

patch, test and relnote note
Make cast expression one of simple expressions expanded into assignment block.
