I did click on that before, but I suddenly had a thought (I should have had
long ago): it seems my combina
It works for me. Did you click on the box where the logs are supposed to
appear? It will only show the logs when you click there.

I tried with this code:
```
from dataclasses import dataclass
@dataclass
class Point:
x: int
y: int
z = 41
def whereis(point):
w = 23
match point:
case Point(0, 0):
print("Origin")
case Point(0, y):
print(f"Y={y}")
case Point(x, 0):
I tried with this code:
```
from dataclasses import dataclass
@dataclass
class Point:
x: int
y: int
z = 41
def whereis(point):
w = 23
match point:
case Point(0, 0):
print("Origin")
case Point(0, y):
print(f"Y={y}")
case Point(x, 0):
+1
Is there a reason, after all, why we should mark constant patterns as
special, and not the opposite?

It also won't work as intended, because 'case z' will always match
and it will never get to 'case .z'.

It sounds like you want to add "global z" to the top of the function definition.
Or more likely, change the last case to 'case _'.

For some value of work: if z comes before .z, the .z branch will never
get evaluated, because the b
