It is possible to write bad code in any language. Haskell tries really hard to eliminate a whole class of problems but the type system doesn’t encompass/express things like thrown exceptions. This seems like a hole in the type system… and yes there are always better ways of doing things but many libraries are written to standards beneath those best practices or written to much older best practices.

The issue isn’t what the language is capable of in the best case. The issue is what the community has produced for future members of the community to consume. See my other comment about pcap and gnuplot for two specific examples.
