When leaving out the first parameter of list(...) EA thinks the second one is the first and suggests adding the $limit parameter to explode(...) which changes the behavior of the code.

The inspection doesn't get triggered.
Confirmed.
[ , $b ] = explode(',', 'a,b,c,d');
// Should suggests:
// explode(',', 'a,b,c,d', 3);
// But suggests:
// explode(',', 'a,b,c,d', 2);
Additionally, it is not triggered when have more than one variable:
[ $a, $b ] = explode(',', 'a,b,c,d');
// Should suggests:
// explode(',', 'a,b,c,d', 3);
Will fix! Thank you for reporting @jdreesen and @rentalhost for confirming.
Fixed!
