Function resolve 

pub fn resolve<F>(
    bundle: &Value,
    members: &[Value],
    template: &str,
    parts: &[Value],
    globals: F,
) -> Result<ScopeOutput, ScopeError>
where
    F: Fn(&str) -> Option<ScopedValue>,

Resolve {local} and {slot.field}. globals returns a value only when the caller can resolve and read that reference; callers should mark a reference secret unless its source is explicitly public.
