I'm not sure what you mean. Look:

So you have opened a file handle to append to the scalar $string.

And now you have printed "here is my string..." to that file handle. If you
examine the contents of $string you will see that it has worked.
Now $string eq "here is my string..." and $scalar_fh is a file handle (a glob
reference) so I don't understand what you're trying to do here.

There is only one item in your list, $scalar_fh, so the loop is executed once,
and it is the same as
print "$scalar_fh";
Perl tries its best to display the value of the file handle, but it's not a very
meaningful thing to do.
Do you mean just this?
print $string, "\n";
