Note that for Mac toolbox functions, the normal syntax is:

  my $foo = MyFunction($bar) or die $^E;

That is, Mac toolbox functions normally return undef on error, and put the
error message in $^E.

(For those playing along at home, Mac::Glue does this differently, by not
necessarily returning undef only on error, but it still puts the error in
$^E.)
