[wxperl-users] Behaviour change for 0.15

[Mattia B. <mb...@ds...>]

[ convention: MyFoo derives from Wx::Foo,
  e.g. MyFrame derives from Wx::Frame ]

Until now calling Wx::Button->new and MyButton->new
returned an HASH refence, so it was possible to use code like this:

my $b = Wx::Button->new( ... );
$b->{foo} = 1; $b->{BAR} = 2;
...

I'd like to deprecate that feature and have
Wx::Button->new( ... ) return a scalar reference,
while MyButton->new( ... ) will still return an
hash refernce; this will help saving some memory,
and is something that I wanted to do since some time,
but I always got more important things to do...

The plan is that there will be a
Wx::_work_as_before( bool ) function to preserve the
current behaviour; until 0.15 this function
will be on by default (but can be switched off),
starting from 0.16 it will be off by default
(but can be switched on).

Comments?
