Language: Magic constants __CLASS__, __METHOD__, __NAMESPACE__, __FUNCTION__

[PurHur]

Problem

#85 covers __DIR__, __FILE__, __LINE__. OOP web code also needs __CLASS__ in templates and logging.

Goal

Resolve magic constants at compile time or runtime per PHP rules.

Tasks

• Extend constant fetch in lib/Compiler.php for class/method context
• VM: populate from active function/class frames
• JIT: embed literals when statically known
• PHPT inside namespaced class method (Language: PHP namespaces (namespace, use, qualified names) #84)
• Update DevEx: Builtin capability matrix (VM / JIT / AOT per function) #176 matrix

Acceptance criteria

class C {
    public function id(): string { return __CLASS__ . '::' . __FUNCTION__; }
}
echo (new C)->id(); // C::id

Dependencies

• Language: PHP namespaces (namespace, use, qualified names) #84 namespaces
• Language: Class methods and property access in JIT #58 class methods in JIT

Files

• lib/Compiler.php, lib/VM.php
