Incorrectly generates code for 'set' return type.

If return value is the 'set<type>', where type is sctruct, for example:

struct Result
{
1: string response;
2: i32 count;
}
service URLScheduler

{ set <Result> getResult(); }

produced the following deserialize code:

/^0$/ && do{ if ($ftype == TType::SET) {
{
$self->

{success} = {};
# ...
$elem5 = new XXX::Thrift::Result();
$xfer += $elem5->read($input);
$self->{success}->{$elem5} = 1;

which gives { "XXX::Thrift::MyType=HASH(0x935b818)" => 1, ... }

Clearly, this is not true for the classes. It seems that this will not prevent something like that:

$self->{success}

->{$elem5} = ref $elem5 ? $elem5 : 1;
