2     Name: Memoize
3     What: Transparently speed up functions by caching return values.
4     Version: 1.00

9     How to build me:
10    
11     perl Makefile.PL
12     make
13     make test
14    
15     There's a very small chance that the tests in speed.t and
16     expire_module_t.t might fail because of clock skew or bizarre system
17     load conditions. If the tests there fail, rerun them and see if the
18     problem persists.
19    
20     If the tests work,
21    
22     make install
23    
24     If not, please send me a report that mentions which tests failed.
25     The address is: mjd-perl-memoize+@plover.com.

37     0.62 was the fist version that would be distributed with Perl.
38     I got so absorbed in integrating it that I wrote some tests
39     that used Time::HiRes. I knew this was safe because
40     Time::HiRes is also distributed with the same versions of
41     Perl. I totally forgot that some people will get the module
42     off of CPAN without Perl and they may not have TIme::HiRes.
43     Sorry!

53     ** The TIE option is now strongly deprecated. It will be **
54     ** permanently removed in the NEXT release of Memoize. **
55     ** Please convert all extant software to use HASH instead. **

61     I'm sorry about this. I hate making incompatible changes. But as of
62     v0.65, Memoize is included in the Perl core. It is about to become
63     much more difficult to make incompatible interface changes; if I don't
64     get rid of TIE now, I may not get another chance.
65    
66     TIE presented serious problems. First, it had a bizarre syntax. But
67     the big problem was that it was difficult and complicated for
68     expiration manager authors to support; evern expiration manager had to
69     duplicate the logic for handling TIE. HASH is much simpler to use,
70     more powerful, and is trivial for expiration managers to support.
71    
72     Many long-awaited cleanups and bug fixes.
73    
74     Memoize now works under threaded perl
75    
76     Slow tests speeded up. More test file improvements.
77    
78     Long-standing LIST_CACHE bug cleared up---it turns out that there
79     never was a bug. I put in tests for it anyway.
80    
81     Manual increased.
