Module value 

VM-specific value representation. VM-specific value representation.

Simpler than sui_eval::Value — no thunks, no rnix AST references. The bytecode VM handles laziness through its own mechanisms; values here are always fully evaluated.

String Interning

Attribute set keys use Symbol handles instead of heap-allocated Strings. This makes key comparison O(1) (integer equality) instead of O(n) (byte-by-byte string comparison). The interner is shared between the compiler and VM via Rc<RefCell<Interner>>.

Structs

HigherOrderBuiltin

A partially-applied higher-order builtin that needs VM access to call user closures.

VMBuiltin

A built-in function callable from the VM.

VMClosure

A compiled closure: the function’s bytecode chunk plus captured values.

VMThunk

A lazy thunk with memoization and blackhole detection.

Enums

HigherOrderOp

Tag identifying which higher-order operation a partially-applied builtin represents.

StringKeyedValue

A string-keyed value for external API consumption.

ThunkState

State of a thunk’s evaluation lifecycle.

VMValue

A value in the bytecode VM.
