Ran into this issue with the following ordering bug:
auto tmpfilename = fn.dup ~ ".XXXXXX\0";
int fd = mkstemp (tmpfilename.ptr);
scope (failure) remove (tmpfilename); // bug:
if (fd == -1)
throw new Exception (strerror(errno).to!string);
The error thrown was
Failed to remove file ...
Is there any work in progress to chain the exceptions in
scope(failure)?
