i2ctarget.I2Ctarget(board.SCL, board.SDA, [0x41]) fail, must use I2CPeripheral

Code/REPL

import board

#from i2ctarget import I2CTarget
#target = I2Ctarget(board.SDA, board.SCL, [0x41])
# ^^^ FAIL with: File "code.py", line 4, in <module> | NameError: name 'I2Ctarget' is not defined

import i2ctarget
#target = i2ctarget.I2Ctarget(board.SCL, board.SDA, [0x41])
# ^^^ Fail with: File "code.py", line 8, in <module> AttributeError: 'module' object has no attribute 'I2Ctarget'

target = i2ctarget.I2CPeripheral(board.SCL, board.SDA, [0x41])
# ^^^ This is actually working

while True:
    request = target.request()
    if request is not None:
        if request.is_read:
            print("Write request ")
            request.write(b'B')
        else:
            r = request.read()
            if r == "T":
                print("Read a T")

Behavior

Failure message are included in the code.
The code is almost identical to example in #6758 (except for the pin in use), but it fail.
The only way to make it work is to use the "old" naming target = i2ctarget.I2CPeripheral(board.SCL, board.SDA, [0x41]).

Description

No response

Additional information

I did not investigate further on other hardware, so I don't know if this is RP2040 specific.

It's I2CTarget not I2Ctarget, see https://github.com/adafruit/circuitpython/blob/main/shared-bindings/i2ctarget/__init__.c#L98

Thanks, I did copy and paste multiple time from #6758 first message.
Or maybe copying the target from i2ctarget just after an I2C and each time I made the case error.
I could not understand as I knew the two were aliases.

This is working (but somehow unstoppable by ^C):

import board
from i2ctarget import I2CTarget

target = I2CTarget(board.SCL, board.SDA, [0x41])

while True:
    request = target.request()
    if request is not None:
        if request.is_read:
            print("Write request ")
            request.write(b'B')
        else:
            r = request.read()
            if r == "T":
                print("Read a T")
