Method Details

concat

public static List<Object> concat(Object left,
 Object right)

Concatenates LPC array operands while treating the false sentinel as an empty array.

LPC code commonly writes expressions such as values + 0 when an optional array is absent. The sentinel remains falsey at rest, but array arithmetic treats it as empty.

difference

public static List<Object> difference(Object left,
 Object right)

Computes the LPC array difference while treating the false sentinel as an empty array.
