| 30 | The original code of <a href="http://cgi.di.uoa.gr/~smaragd/fc++/" target="_top">FC++</a> | |
| 31 | was developed by Brian McNamara and Yannis Smaragdakis between 2000 and 2003. | |
| 32 | One of the aims of their work was to implement as mich as possible of the | |
| 33 | Haskell prelude in C++. In the end they achieved a very large part of that | |
| 34 | and went on to implement other similar things not in the Haskell prelude. | |
| 35 | This was made up of a large amount of code written very carefully in a consistent | |
| 36 | style which made it easy to extend it to provide more facilities. | |
| 37 | </p> | |
| 38 | <p> | |
| 39 | At the end of that time, two versions of it existed, FC++ 1.5 and <a href="http://cgi.di.uoa.gr/~smaragd/fc++/boostpaper/" target="_top">Boost FC++</a> which | |
| 40 | was proposed for inclusion in Boost and rejected. Both are documented on | |
| 41 | <a href="http://cgi.di.uoa.gr/~smaragd/fc++/" target="_top">FC++</a>. | |
| 42 | </p> | |

| 44 | After 2003 John Fletcher spent a lot of time developing both these versions | |
| 45 | and adding new features to them. One of the reasons intially was that the | |
| 46 | existing versions could handle only a small number of function arguments. | |
| 47 | He was able to inclrease the limit on the number of arguments and use the | |
| 48 | new version to implement a number of new ideas. No new release has ever been | |
| 49 | made although a draft release 1.5.2 exists. Much of his activity is documented | |
| 50 | by <a href="http://c2.com/cgi/wiki?FunctoidsInCpp" target="_top">FunctoidsInCpp</a> | |
| 51 | where some discussion took place with other people about this work. | |
| 52 | </p> | |
| 53 | <p> | |
| 54 | John discussed with Joel de Guzman how to make <a href="http://cgi.di.uoa.gr/~smaragd/fc++/" target="_top">FC++</a> | |
| 55 | compatible with Phoenix. Joel suggested using Phoenix as a basis for a new | |
| 56 | version of <a href="http://cgi.di.uoa.gr/~smaragd/fc++/" target="_top">FC++</a>. | |
| 57 | </p> | |
| 58 | <p> | |
| 59 | In 2014 John became the maintainer of Phoenix and after spending time getting | |
| 60 | to know it he has now started to fulfil his idea of a new version of <a href="http://cgi.di.uoa.gr/~smaragd/fc++/" target="_top">FC++</a>. What is emerging | |
| 61 | is significantly different from <a href="http://cgi.di.uoa.gr/~smaragd/fc++/" target="_top">FC++</a> | |
| 62 | in the detail of the implementation. In some ways it will be more powerful | |
| 63 | as it is well integrated with the facilities of Phoenix. In other ways it | |
| 64 | will lack some features of <a href="http://cgi.di.uoa.gr/~smaragd/fc++/" target="_top">FC++</a> | |
| 65 | as they can now be implemented in other ways. | |
