TomAugspurger: I *think* this is what we want to do here. This may surprise some users, if their callable either expects or incidentally creates a pandas dataframe.

If a concrete dataframe really is needed, then `df.map_blocks(pd.DataFrame.assign, column=callable)` should be used instead I think.
mrocklin: Is anyone available to review this?

`.assign` leads to different results when using lambda vs not using lambda

`.assign` leads to different results when using lambda vs not using lambda. Please see the example below.

The difference seems to happen only in the divisions limits. I guess this is a bug? Any idea on why this is happening?


### Imports


```python
import pandas as pd
import numpy as np
import dask.dataframe as dd
```

### Create Dataframe


```python
idx = pd.date_range(start='2013-01-01 00:00:00', end='2013-01-01 06:00:00', freq='30t')
df_pd = pd.DataFrame({'col_1':[1,2,3,4,5,6,7,8,9,10,11,12,13,]}, index=idx)
df = dd.from_pandas(df_pd, npartitions=2)
df.compute()
```
