Pharo

Everything in Pharo is an object, including classes and control structures, which eliminates primitives and provides a uniform programming model as highlighted in its key features.

The environment supports real-time code modification and execution without restarting, enabling immediate iteration and debugging, core to its philosophy of simplicity and feedback.

By merging the IDE and OS into one cohesive experience, Pharo reduces context switching and tool fragmentation, offering a seamless development process as described in the README.

Pharo's reflective capabilities allow runtime introspection and modification of code, facilitating advanced debugging and exploratory programming techniques.
