Way to retrieve value of properties in `pipe`

To execute a method of an object, I can do something like:

# Executes the `describe` method of `mtcars`
mtcars >> pipe(_.describe())

However, when I want to retrieve a property of an object, this does not work:

# Want to get `mtcars.columns`
mtcars >> pipe(_.columns)

█─'__call__'
├─█─.
│ ├─_
│ └─'columns'
└─     mpg  cyl   disp   hp  drat     wt   qsec  vs  am  gear  carb
  0   21.0    6  160.0  110  3.90  2.620  16.46   0   1     4     4
  1   21.0    6  160.0  110  3.90  2.875  17.02   0   1     4     4
  2   22.8    4  108.0   93  3.85  2.320  18.61   1   1     4     1
[...]

The closest I could get was:

mtcars >> pipe(lambda _: _.columns)

Index(['mpg', 'cyl', 'disp', 'hp', 'drat', 'wt', 'qsec', 'vs', 'am', 'gear',
       'carb'],
      dtype='object')

But it would be really cool to retrieve properties directly from the Symbolic instance.

Hey–thanks for raising. I get bit by this pretty regularly, and its a quick fix! I opened a PR, and will merge later today 😃.

(Will take a closer look at your comments on piping issues. It feels like a few pipe changes would go a long way.)

Sorry for the wait–should be available in v0.0.25!
