Notes on Table 5

1. EDT won't support every variation of RBD's move statement. There will be support for move byName, move for, and move for all. A move statement without one of the additional keywords is only allowed between two references, and it results in the target being assigned a copy of the source's value. If/when we support structured records, we might not support move byName on them because of the complex (unclean) design.
2. EDT doesn't have called programs, but services and native programs can be called.
3. EDT's foreach statement will support iterating over an array.
4. Support for these statements is tentative, pending the design for JPA in EDT.
5. New syntax will allow setting annotations on declarations without the use of curly braces. In RBD we usually do x int {myAnnotation = 3}; but another way to do the same thing is x int {@myAnnotation{3}};. In EDT we will allow that to be outside of curly braces and before the declaration, for example @myAnnotation{3} x int;.
