November 2019 bugfixes

When using continue within switch statements, special care has to be taken to ensure the loops are continued as expected. This release removes ambiguity by specifying the continue nesting argument.

From https://www.php.net/manual/en/control-structures.continue.php :

Note: In PHP the switch statement is considered a looping structure for the purposes of continue. continue behaves like break (when no arguments are passed). If a switch is inside a loop, continue 2 will continue with the next iteration of the outer loop.
