No-one has the time to learn all these languages, so for those of us not in the know, the most generous we can be is to take these praise articles at face value. And these articles are typically 'dynamic good', 'static bad'.
From the article:
they insist on a statically typed worldview leading to parochial, snowflake APIs that defy abstraction and higher level manipulation, or both.
So I guess the user base for this language is those developers who think dynamic is better than static, and go for (as-static-as-Java) Closure.
