he’s very familiar with C and C++. In his associated writeup on his Gopher page (link though Floodgap) [jns] simply declares it’s a language he’s quite fond of, which is reason enough of us.
So there are no technical reasons to do so. Its totally understandable to like and use a language for personal feelings. But it kinda feels like unnecessary complicated. So this should be done as a hobby project on something that is not important in my opinion.
Make it in Haskell if you want impress me.
