Magpie [1] was an initial effort as a summer of code project. The 
last commit was September 2019.

There is also some basic support in mir (example at [2]). Ilya 
can speak more about long-term plans for enhancing that.

One limitation in mir is that Slice's only allow for the same 
type throughout. For instance, a Slice!(double*, 1u) is a 
1-dimensional slice of doubles. Data frames in R or Pandas 
DataFrames allow for columns with different types, so for 
instance you can calculate some summary statistic based on some 
category (like color). So to really get the same functionality, 
you need to support slices with heterogeneous types.
