It's handled using a type safe GValue conversion in language bindings.
g_object_set is just a convenience method for C which coverts the parameters
to the GValue's the properties expect.

It's not really possible to introspect argument type in runtime and the
compiler is not smart enough to tell you that the argument is wrong.

You could use g_object_set_property instead, but that's rather verbose in C.
Ah well.
