Struct BopFn 

pub struct BopFn {
    pub params: Vec<String>,
    pub captures: Vec<(String, Value)>,
    pub body: FnBody,
    pub self_name: Option<String>,
}

A Bop function value — the runtime representation of a closure or a reified fn foo(...) { ... } declaration. Shared by Rc so first-class usage (let g = f; pass(f)) is cheap.

The body is engine-opaque: the tree-walker produces an FnBody::Ast for direct interpretation; the bytecode VM produces an FnBody::Compiled carrying a pre-compiled body. Each engine only ever dispatches its own variant.

Fields

params: Vec<String>

captures: Vec<(String, Value)>

Values captured from the enclosing scope at construction time, cloned by value. Free variables in the body that aren’t parameters and aren’t in this list fall through to the outer module / global lookup at call time.

body: FnBody

self_name: Option<String>

Some(name) when this BopFn is bound to its own name for self-reference (the lowering of fn foo(...) { ... }). Lambdas created from an fn(...) { ... } expression leave this None.
