If the language is the hard part, something is wrong with it.
Usually. I've seen and user a whole slew of opinionated languages, and they almost always have a big chunk of problems they will be awkward to use for, or even almost insoluble.
Every succesful one supports multiple programming paradigms, better or worse, usually decently.
Now the real stuff that can cause problems is bad tooling and lack of support. You cannot code your things when you're trying to fix the compiler, build tools or the debugger.
