Problem
If your syntax has nullable expressions
[%-direction% %-location%]
and used directlyexpression = Direction.combine((Expression<Direction>) exprs[0], (Expression<Location>) exprs[1]);
it'll throw a null pointer on use.Solution
Rather than having to check if both expressions are null before calling the combine method, you can now properly do the single line call, and the returned expression will be the expected null if the syntax was wanting the expression to be null if not present.
