Others have discussed that particular case at length, but to
provide a more generic answer the correct way to translate a
python context manager is to use scope(out):
{ // Scope restriction similar to with's block
auto f = File("x.txt");
scope(out) f.close(); // closes f on scope exit no
matter what
/* do stuff with f */
}
This accurately reproduces the behaviour of python's with
although it's less automatic.
what is `scope(out)`? I only know these
