Hi,
there seems to be a bug when a property gets deleted inside 'with'.
(Of course 'with' shouldn't be used in the first place, but I was
helping somebody on IRC who had inherited the code.)
Here's the description of the 'phenomenon', observed with Mtasc that
came with FD3 beta 2:
>>>
// both swf's contain this exact same class
// one compiled in Flash, one compiled in FlashDevelop
// Flash gives undefined, FlashDevelop gives 10 in a trace.
class Test
{
public function Test()
{
var o = new Object;
o.i = 5;
with(o) {
delete i;
i = 10;
}
trace(o.i);
}
}
<<<
Flasm shows the difference between the two compilers:
// mtasc
with
push "i"
getVariable // <-- shouldn't be here!
push 1, "delete"
callFunction
pop
push "i", 10
setVariable
end
// flash
with
push "i"
delete2
pop
push "i", 10
setVariable
end
Also, I'm curious -- why does Mtasc call delete as a function?
