https://issues.dlang.org/show_bug.cgi?id=23159 Issue ID: 23159 Summary: [betterC] scope(failure) use in betterC gives confusing error Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: jack jackstouffer.com ``` void main() { scope(failure) { int a; } int b; } ``` Gives ``` $ 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. --
