This has been discussed (recently in fact) and won't be done. However,
you *can* give your code the type of readability you're looking for with:
($condition) || {
/* This will only run if $condition evals to false */
}
Or, if you absolutely want that unless() structure in there, you can
create a simple wrapper for it:
unless($condition) || {
/* This will only run if $condition evals to false */
}
function unless($condition) {
return $condition;
}
This makes "unless()" a useless function and wastes clock cycles, but
allows your code to look almost exactly like you're wanting.
You *might* want to type cast $condition to (bool)....
