Tab completion invokes property

[dhalbert]

Hitting tab to auto-complete a property name invokes the property.

testtab.py:

class C:
    @property
    def oops(self):
        print("OOPS!")

in REPL:

Adafruit CircuitPython 5.4.0-beta.1-37-g2b652e1d1-dirty on 2020-06-19; Adafruit Metro M4 Express with samd51j19
>>> import testtab
>>> c = testtab.C()
>>> c.oops
OOPS!
>>> c.oo<TAB>OOPS!     # <TAB> is where I hit the tab key
ps

Yes! Please! I'm sorry I didn't think to report this because it bites me regularly

cpython 3 does this as well.

>>> import oops
>>> c = oops.C()
>>> c.oo<tab>OOPS!
ps

It's not a bug, it's a feature. Oy. 🤦
