If you restart SDM, then no. Hot-patching and expression evaluation are definitely things we've discussed (I want to build an Apple XCode/Swift Playground-like REPL for fun myself), but first we've got to make the normal SDM experience out of the box great, including IDE integration and super-fast recompile. Once we get there, hopefully we can do the other things and reach a state that was better than DevMode was. -- > You received this message because you are subscribed to the Google Groups > "GWT Contributors" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to google-web-toolkit-contributors+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/google-web-toolkit-contributors/5a2a4436-5c2d-4e60-9d5d-314db0045b7d%40googlegroups.com > <https://groups.google.com/d/msgid/google-web-toolkit-contributors/5a2a4436-5c2d-4e60-9d5d-314db0045b7d%40googlegroups.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "GWT Contributors" group.
