new match statement and types

[Robin Becker]

I'm trying out new features in 3.10.0a6 looking at the new match statement I tried it with various cases. Knowing that 
the class of a class is 'type' I tried using match to distinguish between classes and instances so I tried various 
versions of

#######################
class A:
	pass

class B:
	pass

def tmc(C):
	match C:
		case type(__name__='A'):
			print(f'{C} is an A' )
		case type():
			print(f'{C} is a type' )
		case A():
			print(f'{C} is an A instance')
		case _:
			print(f'{C} is an instance')

if __name__=='__main__':
	tmc(A)
	tmc(B)
	tmc(A())
	tmc(B())
#######################

the above seems to work and produces

> <class '__main__.A'> is an A
> <class '__main__.B'> is a type
> <__main__.A object at 0x7fe5a2248fd0> is an A instance
> <__main__.B object at 0x7fe5a2248fd0> is an instance

is this the right approach to this problem of distinguishing instances ?
