nl_tokens: The base implementation of methods like _ . xor without support for iteratee shorthands that accepts an array of arrays to inspect .
pl_tokens: function baseXor ( arrays , iteratee , comparator ) { var index = - 1 , length = arrays . length ; while ( ++ index < length ) { var result = result ? arrayPush ( baseDifference ( result , arrays [ index ] , iteratee , comparator ) , baseDifference ( arrays [ index ] , result , iteratee , comparator ) ) : arrays [ index ] ; } return ( <mask> && result . length ) ? baseUniq ( result , iteratee , comparator ) : [ ] ; }
