Notes on Table 5
- 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.
- EDT doesn't have called programs, but services and native programs can be called.
- EDT's foreach statement will support iterating over an array.
- Support for these statements is tentative, pending the design for JPA in EDT.
- 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;.
