+- Why such name ?
+ - In short: it's just a number.
+ - Many years ago inspired by the ideas of [[https://en.wikipedia.org/wiki/Forth_(programming_language)][Forth (programming
+ language)]] I decided to create my own implementation [[http://www2.svjatoslav.eu/gitbrowse/fifth/doc/index.html][Fifth]]
+ (computing/programming environment).
+ - Then I realized I miss type safe object oriented capabilities. So
+ I updated the name to Sixth and switched to Java.
