Good to know. I think a small dependency is fine. There are precious few languages that allow a static binary. I wonder what the size would be though. HelloWorld in Nim is ~10 MB, although there may be an optimization setting I skipped. GForth can't make standalone executables though and doesn't have good beginner information either. I'm also under the impression that Forth shines best as a special purpose implementation for that particular project (how Chuck Moore does it). Not sure if Kitten works better as a general purpose language or not yet, but i like the concepts so far.
I downloaded Nim last year, wrote the line: echo "Hello World" , and then used the Aporia IDE's feature to compile to executable I believe. That or the command-line method. This was on Windows and the resulting exeutable was indeed sized around 10 MB. I did state that there could have been more optimizations like a release mode flag.
Edit:
The sizes in the link you submitted are very small and rational (what I was expecting to see). I can't remember what it does on Windows without GCC. It might have used Cygwin, but it should have still not been orders of magnitude bigger. This turned me off immediately.
