          Issue ID: 19944
           Summary: Some examples on std.file docs page raise
                    FileException
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor
          Priority: P1
         Component: dlang.org
          Assignee: nobody at puremagic.com
          Reporter: a at b5.re

For example, pressing "Run" on the example for timeLastModified causes the
following error:

std.file.FileException@/dlang/dmd/linux/bin64/../../src/phobos/std/file.d(1675):
/tmp/deleteme.dmd.unittest.pid25: No such file or directory

Changing deleteme.write("bb") to std.file.write(deleteme, "bb") causes it to
work (and phobos unittests still pass), but I'm not sure why.

Another one that fails using the same pattern is the 2nd example of
mkdirRecurse.
