Function c__

Captures the input value for the current thread.

If no name is provided, it generates a default name.

Example

c__(x);

c__(x, { name: "var-name" });
c__(x, { name: (index, allowIndex, value) => `${index}` });

[1, 2, 3, 4, 5].map(i => c__(i, { allow: (index, name, value) => index > 2 }));
[10, 20, 30].map(x => c__(x, { allow: (index, name, value) => value === 20 }));

const z = d__(() => c__(outside_1) + y * c__(outside_2) + d__(() => k * c__(inside(5),
  { level: 1 })));
