(Not specific to this language and I'm not vouching for this in any way, but:)

I think one argument would be that the language seems to be effect based.

This allows you to control what a program can do without auditing the code.

I see the point you mention, in that case, I think a language like Haskell is the better choice, so it could be marketed as an "agents" language that hit the market three decades before today’s agents :)
