> As a face-value claim, that's obviously untrue. Forth, by any reasonable metric, is a smaller language than Go, but I think you'd have a hard time claiming it's more productive.

I used Forth instead of Awk recently. What I wanted to do required to be more proficient than I am in Awk, while I am proficient in Forth. As you probably know, Forth is not exactly a string-oriented language.

There's no language more productive than others. But there are triplets (programmer, language, task) that are more productive than others.
