Huh???  What would it break?  And I don't see how it would be confusing (in
fact, in my opinion it would be exactly the reverse).

Choosing between "case 0:" and (say) "case_identical 0:" would only be the
same as choosing between == and === in an if statement -- it would just give
the opportunity to do it using the elegant switch structure instead of the
clumsy if...elseif...else chain.

It just seems a shame not to have an === equivalent available within switch
structures -- but, hey, it was only a speculative suggestion, I'm perfectly
happy to bow to contrary opinion, and this is absolutely my last word on the
subject ... ;))

Cheers!

Mike

Why not something like this:

$a = 0;

switch (true) {
  case ($a === 'somestring'):
    ...
    break;
  case ($a === 0):
    ...
    break;
}

It's not pretty, but you might like it better than
if...elseif...else...
