Convert an object of map type to string type

As this example shows, even though the outputs look the same, they are different.

Code

var( People_Map = map('President' = 'John Doe',
                     'Vice President' = 'Jane Doe', 
                     'Treasurer' = 'Joe Surname', 
                     'Secretary' = 'John Doe') )

var( People_String = $People_Map->asString )

'People_Map: '+$People_Map+', is type: ' + $People_Map->type + '\n'

'People_String: '+$People_String+', is type: ' + $People_String->type

Result

People_Map: map(President = John Doe, Secretary = John Doe, Treasurer = Joe Surname, Vice President = Jane Doe), is type: map
People_String: map(President = John Doe, Secretary = John Doe, Treasurer = Joe Surname, Vice President = Jane Doe), is type: string
