• rust

  2,682 92,831 10.0 Rust

  Empowering everyone to build reliable and efficient software.

  

For that, placement new has been recognized as a desirable feature all along. The problem is that coming up with an implementation that doesn't require unsafe and that Rust developers are willing to commit to supporting until the end of time is harder that it looks. (See the discussions in issues like #27779 and #64062 if you want to get up to speed on how it's harder than it looks.)

• Mockito

  11 14,584 9.0 Java

  Most popular Mocking framework for unit tests written in Java

  

A lot of that magic on the JVM (Mockito / Spring Boot) relies on proxy objects that intercept method calls, and operate on them in a non-typesafe manner (working on Object[] args, and returning Object). When you use them, it looks type-safe, but under the hood it's all dynamic. Here is an example in Mockito: https://github.com/mockito/mockito/blob/ea000f72444ed4c7e409441aedc3021951b89660/src/main/java/org/mockito/internal/creation/bytebuddy/MockMethodInterceptor.java#L59.
