Dartium can now pause on exceptions, including checked mode.
In the Dart Editor we fixed 29+ issues in the static analyzer, added new syntax coloring to highlight the use of var variables, and to distinguish member and static fields from local variables (aka semantic highlighting). We added new syntax coloring to show other uses of the currently selected variable (aka mark occurrences), added support for the "as" operator, added a warning if the + operator is used with strings. Finally, when debugging a command-line app, the debugger will break on uncaught exceptions (TypeError and AssertionError). More to follow on the debugging story.
