*<blockquote></blockquote><u>'''This document is not finished yet!'''</u>

*This document was populated from design meetings. Meeting notes are at [[EDT:Discussion topics from the language meetings]].
 +
*"N/S" means Not Supported. We may support N/S features in the future.
 +
*Anything that exists in RBD but isn't mentioned here is not included in EDT. Or maybe we forgot about it. Nobody's perfect.<br>  
 +
*The work in the Core category includes the parser, model, and validation.<br>
 +
*The work in the JavaScript, Java, and Debug categories includes both the generator and runtime.<br>
 +
*Text <span style="background:#FFA500">with an orange background</span> shows differences in features supported by both EDT and RBD.
 +
*Features <span style="background:#FFFF00">with a yellow background</span> are planned for EDT 1.0, but not EDT 0.7.0.
 +
*'''Developers:''' include a link to Bugzilla for features not done yet, and mark items "Done" when you're finished.

#In RBD, a move statement between two references does a deep copy. Reference types should include a deep copy function to provide the same functionality in EDT.<br>
+
−
#EDT doesn't have called programs, but services and native programs can be called.<br>

−
#EDT's foreach statement will support iterating over an array.<br>

−
#Support for these statements is tentative, pending the design for JPA in EDT.<br>

General Notes

  • This document was populated from design meetings. Meeting notes are at EDT:Discussion topics from the language meetings.
  • "N/S" means Not Supported. We may support N/S features in the future.
  • Anything that exists in RBD but isn't mentioned here is not included in EDT. Or maybe we forgot about it. Nobody's perfect.
  • The work in the Core category includes the parser, model, and validation.
  • The work in the JavaScript, Java, and Debug categories includes both the generator and runtime.
  • Text with an orange background shows differences in features supported by both EDT and RBD.
  • Features with a yellow background are planned for EDT 1.0, but not EDT 0.7.0.
  • Developers: include a link to Bugzilla for features not done yet, and mark items "Done" when you're finished.
