[Python-Dev] Re: PEP 622 (match statement) playground
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):
print(f"X={x}")
case Point():
print("Somewhere else")
case 23:
print("Not the answer")
case w:
print("Not the answer, local w")
case z:
print("The answer")
case _:
print("other")
whereis(42)
```
The output is:
```
Not the answer, local w
<>:23: SyntaxWarning: unguarded name capture pattern makes remaining cases
unreachable
<>:23: SyntaxWarning: unguarded name capture pattern makes remaining cases
unreachable
:23: SyntaxWarning: unguarded name capture
pattern makes remaining cases unreachable
case w:
```
I except this function to return "other", But it seems not.

It retuend:
```

unreachable
<>:23: SyntaxWarning: unguarded name capture pattern makes remaining cases
unreachable
:23: SyntaxWarning: unguarded name capture

case w:
```
It seems not the return I except.
