I was recently switched from Java to C# at work.

Initially I was impressed by the null detection. Then I found out about defaults. Way worse than null.

C and Go can demand a bit of ceremony with manual error checks. Things get bad if you forget to do the checks.

Java and Checked exceptions forced error-checking, which is a little verbose, and most of the time you can't 'handle' (for any meaning other than log) them, so you just rethrow.

C# went with unchecked exceptions. But with default values, there's no need to throw! Avoid Java's messy NPE encounters by just writing the wrong value to the database.

Default value is only relevant for structs. You can setup an analyzer rule to ban this for structs which have, say, an empty constructor. It’s a similar problem to Go and C++ except it’s worse in the latter two.
