Description

Exclusive or operator.

Returns

If there's a single argument, that argument will be returned.

If there are more than two arguments, the result will be: `^(`^(arg1, arg2), @extras).

If arg1 is an object that has an lfun::`^, that function will be called with arg2 as the single argument.

If arg2 is an object that has an lfun::``^, that function will be called with arg1 as the single argument.

Otherwise the result will be as follows:

arg1 can have any of the following types:

int The result will be the bitwise xor of arg1 and arg2. mapping The result will be the elements of arg1 and arg2 that only occurr in one of them. string The result will be the pairwise bitwise xor of arg1 and arg2. object(type) The result will be the result of (arg1&~arg2)|(~arg1&arg2).
