Trace slice error: "Stop value in slice not suported"

If you refer the source (of PyMC3) you can observe that this error can be avoided only by setting the stop value in the slice to none. It seems for some reason PyMC3 does not support slicing the stop index.

"""Text file trace backend

Store sampling values as CSV files.

File format
-----------

Sampling values for each chain are saved in a separate file (under a
directory specified by the `name` argument).  The rows correspond to
sampling iterations.  The column names consist of variable names and
index labels.  For example, the heading

  x,y__0_0,y__0_1,y__1_0,y__1_1,y__2_0,y__2_1

represents two variables, x and y, where x is a scalar and y has a
shape of (3, 2).

I’m very curious to know why isn’t it supported?
@junpenglao any ideas?
