We should have used x and y instead of x and t, to match the C++ mangling:

$ c++filt -t x y
long long
unsigned long long

At the very least it would be easy to decode the types using the c++filt 
command-line tool and the abi::__cxa_demangle function already built in the 
standard C++ library.

It's a little saner because the signed ones use the expected letters and the 
unsigned ones are just the next letter (except for the chars):

					C++					D-Bus
				signed	unsigned	signed	unsigned
char / 8-bit		a		h		 			y
short / 16-bit		s		t			n		q
int / 32-bit		i		j			i		u
long				l		m
long long / 64-bit	x		y			x		t
__int128			n		o

				C++		D-Bus
bool			b		b
float			f		f (non-standard)
double			d		d
long double		e
__float128		g
