It would be dishonest not to point out that despite it's utility to hackers, Scheme shares Haskell's unsuitability for production code. The difference is that Scheme is limited by its minimalistic standard library, not by a flaw in the language, and you can "upgrade" to a syntactically similar, but heavyweight, cousin such as Common Lisp, or Clojure, to get work done.

I wonder if there's something to this notion. Would it be useful to study the "standard" libraries of various languages to determine what constitutes "suitability for production code?"

Most likely, everything is relative to the particular application a shop wants to build.
