Bug description:Support strict switch

Description:
------------
Currently switch() are loose (as said on doc), but it should be strict
by using a keyword. It's need to avoid somekind of hacks:

Suggestion:

    strict switch ($value) ...
    switch strict ($value) ...

Or, is possible improve a lot the strict by accept an operator. It
should compare the switch value with case value:

    switch == $value ... or 
    switch == ($value) ...

    switch === $value ...
    switch >= $value ...
    switch < $value ...

So you can do something like that:

    switch >= $strength {
        case 0: return 'weak';
        case 40: return 'medium';
        case 80: return 'strong';
        case 100: return 'perfect';
    }

Currently it's possible by 'hacking' that:

    switch (true) {
        case $strength >= 0: return 'weak';
        case $strength >= 40: return 'medium';
        case $strength >= 80: return 'strong';
        case $strength >= 100: return 'perfect';
    }
