Attempt to cast before failing?

[richplane]

When setting a property wouldn't it be reasonable for Synthesize to attempt to cast to the desired type before throwing a TypeException ?

For instance:

$latitude_that_could_be_from_db = '53.4562';
$an_object->latitude = $latitude_that_could_be_from_db;

this throws an exception 'Frozensheep\Synthesize\Exception\TypeException' with message 'Expected value of type Frozensheep\Synthesize\Type\FloatObject, string given'.

It seems like we have a choice of casting everything outside or inside of the Synthesize package; wouldn't be be easier for users of this it if was done inside?
