EZ 3.0 is a ground-up rewrite. The Go interpreter is gone. In its place: a full C compiler backend that takes .ez source, emits C, and produces native binaries.

Highlights

• Native compilation - .ez to C to binary. Real native code.
• Scope-based memory management - arena allocators per scope, automatic cleanup, no garbage collector.
• Pointers - ^Type syntax, new() returns pointers, addr(), auto-deref on struct fields.
• Functions as first-class types - func(int, int) -> int signatures, store them, pass them, return them.
• C interop - import c"stdio.h", call C functions with c.func().
• Wide integers - i256/u256 new, i128/u128 reimplemented as portable structs.
• 27 stdlib modules on native code - plus new modules: @net, @atomic, @mem, @fmt, @sync, @channels.
• Wildcard types - ? for generic-style functions, monomorphised per call site.
• Single embedded binary - one ez binary ships everything.
• 1,200+ tests - unit, e2e, integration, sanitizer builds.

Breaking changes

• temp renamed to mut
• @std removed - all functions are builtins now
• new() returns ^Struct pointers
• bare func removed - use full signatures: func(int) -> int
• import & use replaced by import and use
• nil is a value, not a type
• ez run removed - use ez <file.ez>
