I'm sure it's easy to find annoying problems with ML just as well. We're always left with a choice between being annoyed what's missing or just getting work done. Empirically, complex spaghetti code can be produced in any language. Beyond a certain point (that I suspect has long been crossed) more features only allow for more complexity before it becomes unmanageable (and then the pain is just the greater). Anecdotally, languages and language features, and experimenting how to best employ them (in a particular situation or in general), is also a huge time sink that can detract from actual work.
