PHP Bug Type: *Programming Data Structures
Bug description: return() in short-circuit / lazy evaluation
Description:
------------
please allow return() in lazy evaluation /short-circuit syntax like
$result=do_something($blah) or die('nothing done'); // this works
but
$result=do_something($blah) or return(false) ; // does NOT work
I thing it is prety legitimate not only to call die() if do_something()
return false, but in this case return() from function or include() as well.
I thing it is more cleaner and readable then bunch of
$result=do_something($blah)
if ($result==false){
return false;}
// use you result here
Maybe even codeblock after "or" is worth of considerations
$result=do_something($blah) or { // codeblock, do what you want here
}
