Consider inline perspectives in statements that the source is a variable

[javadch]

In statements that the source clause is a variable, the result set perspective is automatically set to the source perspective. This does not work with the inline perspective. In this case, the inline perspective should be considered as the perspective of the target clause and naturally the result set, too.

Also this case should be supported:
SELECT inline att1 FROM var1 into var2
in that att1 is one of the attributes of the var1's perspective. When executed, the var2's perspective has just att1 as its attribute.
