"static" call to UNIVERSAL::can

Is there some reason why 'can' does not allow a class name,
but (silently) insists on an instance?

I wanted to do this : 

sub Construct
{
 my $class = (caller(0))[0];

 if ($class->can('Something'))
  {
   ...
  }
 else
  {
   ...
  }
}

can just returns undef in this case, even if class has method in
question.

Anyone object to a patch?
