because we could end up with a perl. In perl every task can be done at
least  3 different ways and some constructs can be done 15 different ways
!!!! It is any wonder that many people find perl hard to use.

One of the aims of ant is simplicity. I don't want to have to think while
building build.xml files ;) I am not saying I oppose definigng scripts via
scripting I am still not sure in that case
