          Issue ID: 23159
           Summary: [betterC] scope(failure) use in betterC gives
                    confusing error
           Product: D
           Version: D2
          Hardware: All
                OS: All

          Severity: normal
          Priority: P1

void main()
        int a;
    int b;


$ dmd -betterC main.d
Error: Cannot use try-catch statements with -betterC

Two problems here. One, there's no line number. Two, this does not give any
indication to the user about the true cause of this error. Thankfully I knew
what to look for because I knew that scope(failure) was lowered to a try catch
from a dconf talk.

Really, scope(success)/scope(failure) has no business being in betterC code and
should get its own custom error message.
