or what's the differents between theese two:

}
and:
void transactionalCreate(string filename) {
string tempFilename = filename - ".fragment";
auto f = File(tempFilename, "w");
std.file.rename(tempFilename, filename);
}
I'm a newcomer as well, so take my answer with a good dose of doubt.
There is no difference AFAIK.
scope(success) allows defining end-of-scope process for a given element
--here the file-- in case of success using an idiom consistent with
other possible outcomes (read: exit, failure). I find this a Good Thing,
personly.
