-=head1 NAME
-
-Tie::Memoize - add data to hash when needed
-
-=head1 SYNOPSIS
-
-  require Tie::Memoize;
-  tie %hash, 'Tie::Memoize',
-      \&fetch,			# The rest is optional
-      $DATA, \&exists,
-      {%ini_value}, {%ini_existence};
-
-=head1 DESCRIPTION
-
-This package allows a tied hash to autoload its values on the first access,
-and to use the cached value on the following accesses.
-
-Only read-accesses (via fetching the value or C<exists>) result in calls to
-the functions; the modify-accesses are performed as on a normal hash.
-
-The required arguments during C<tie> are the hash, the package, and
-the reference to the C<FETCH>ing function.  The optional arguments are
-an arbitrary scalar $data, the reference to the C<EXISTS> function,
-and initial values of the hash and of the existence cache.
-
-Both the C<FETCH>ing function and the C<EXISTS> functions have the
-same signature: the arguments are C<$key, $data>; $data is the same
-value as given as argument during tie()ing.  Both functions should
-return an empty list if the value does not exist.  If C<EXISTS>
-function is different from the C<FETCH>ing function, it should return
-a TRUE value on success.  The C<FETCH>ing function should return the
-intended value if the key is valid.
-
-=head1 Inheriting from B<Tie::Memoize>
-
-The structure of the tied() data is an array reference with elements
-
-  0:  cache of known values
-  1:  cache of known existence of keys
-  2:  FETCH  function
-  3:  EXISTS function
-  4:  $data
-
-The rest is for internal usage of this package.  In particular, if
-TIEHASH is overwritten, it should call SUPER::TIEHASH.
-
-=head1 EXAMPLE
-
-  sub slurp {
-    my ($key, $dir) = shift;
-    open my $h, '<', "$dir/$key" or return;
-    local $/; <$h>			# slurp it all
-  }
-  sub exists { my ($key, $dir) = shift; return -f "$dir/$key" }
-
-  tie %hash, 'Tie::Memoize', \&slurp, $directory, \&exists,
-      { fake_file1 => $content1, fake_file2 => $content2 },
-      { pretend_does_not_exists => 0, known_to_exist => 1 };
-
-This example treats the slightly modified contents of $directory as a
-hash.  The modifications are that the keys F<fake_file1> and
-F<fake_file2> fetch values $content1 and $content2, and
-F<pretend_does_not_exists> will never be accessed.  Additionally, the
-existence of F<known_to_exist> is never checked (so if it does not
-exists when its content is needed, the user of %hash may be confused).
-
-=head1 BUGS
-
-FIRSTKEY and NEXTKEY methods go through the keys which were already read,
-not all the possible keys of the hash.
