The Oscar Programming Language

Oscar is a statically typed object-orientation and functional-programming fusioning modern generic programming language.

Rationale

Good design should be idiomatic, bad design should smell.

State and Process

In-Development

The development of the language follows a strongly incremental model. It starts with a language that can only consists of a single integer, and eventually (if ever) develops into a usable langauge.

Differences to Java

Following is an incomplete but representative list of differences between Oscar and Java:

• There is no null. At all.
• There is no inheritance at all, only implementing interfaces is allowed.
• Reduced mutability. There are no mutable local variables or parameters, only instance variables can be mutated, occasionally.
• There are no blocking operations. It is not possible to sleep, wait, synchronize or otherwise block a (system) thread in Oscar.
• There is no explicit threading / coroutines / etc. Everything defaults to asynchronous, including all method calls.
• No primitive values, everything is an object.
• Objects do not have any methods by default. No equals(), hashCode(), toString().
• No instanceof, getClass(), no reflection.
• No serialization.
• No cycles, looping structures.

Syntax

The currently allowed syntax is one integer as text. When compiled and executed, this integer will be returned as exit value.
