Description:
------------
SoapClient::__getFunctions() / SoapClient::__getTypes() now return both an array 
of strings. Each string contains a function signature or a structure description 
respectively. So it's hard to really use this information programmatically. You 
have to parse the strings into something useful first. 

It would be more useful to get a nested array with all information from the 
WSDL. For example __getFunctions() now delivers this:

array (
  0 => 'LoginCustomerResponse loginCustomer(LoginCustomer $loginCustomer)',
  1 => 'FindCustomerResponse findCustomer(FindCustomer $findCustomer)',
  ...
)

it's easier to use this:

array (
  array(
    'name'=>'loginCustomer',
    'returnType'=>'LoginCustomerResponse',
    'arguments'=>array(
      array('name'=>'loginCustomer'),
      array('type'=>'LoginCustomer')
    )
  ),
  array(
    'name'=>'findCustomer',
    'returnType'=>'FindCustomerResponse',
    'arguments'=>array(
      array('name'=>'findCustomer'),
      array('type'=>'FindCustomerResponse')
    )
  ),
...
)

To keep BC i suggest to use default argument:

SoapClient::__getFunctions($asStrings=true) 
SoapClient::__getTypes($asStrings=true)
