it consistently works and has a huge ecosystem, but "beautiful" is never a word I would use to describe java. off the top of my head:
* no type level concept of a const object (ie, you can have a const reference to a List, but never a reference to a const list). this makes const-ness an implementation detail of the class itself! so frustrating that List:add() can throw depending on the underlying class.
* lack of tuples (and no, record doesn't count). this is just a syntactic sugar thing, but I really miss it from c++ and python.
* var is far less powerful than c++ auto.
in most cases, I actually prefer the syntax of c++, which is really saying something.
