[londonperl] Re: disable auto-instantiation or warn about it

[Frank v Waveren]

Disabling or warning for it would prevent bugs that go:

if ($object->{"thingy"} == 42) 
{ 
   # Do stuff;
}

...
# Lots of code
...

if ($object) 
{ 
    # We've been passed an object. We do lots of stuff with it
    # which then crashes mysteriously once in a blue moon, and 
    # you have to trace back to whatever set $object to {} in
    # in the first place
}
