I don't think for a second that there's anything special about isX functions
which make it so that they can't throw. It all depends on what they're doing.
If they can't throw, then they're marked with nothrow.

And while the stat call may be an implementation detail, regardless of how
isFile, isDir, or isSymlink are implemented, they rely on the fact that the
file that they're given exists, so _of course_ there's going to be a serious
problem if the file doesn't exist. Throwing is the correct behavior in that
case.
