It also doesn't have first class records. A record is nothing but a tuple, with some compile-time sugar that reminds you what the fields are. If Employee records have a name field, then you access it by saying e#Employee.name.

Rewrite in the past tense, and this is an epitaph for any number of "niche" languages. Sad but true. Computer programming would be much better off if it were not so. Cultural expectations are a major factor in initial impressions. Good initial impressions make for a large, vibrant user base.

Python probably "gets it right" in terms of having enough syntax to satisfy expectations, but little enough to make tool writing accessible. (Except for the indentation thing, of course.) Ruby has too much. Smalltalk drops the ball with no precedence rules for math operations. Lisp and Forth are also a bit too weird, especially if your field is not programming and all you want to do is crunch some engineering data.

Now Smalltalk and Lisp have both been used for "systems programming" -- years ago, on much older hardware. One can just live with the overhead. Go looks like it would have C-like memory overhead, so perhaps it is a much better choice in this regard?
