[datatable-help] Stability of Duplicate Column Renaming in Version 1.9.3

[Christian Sigg]

We are evaluating data.table version 1.9.3 to benefit from a number of 
bug fixes. But one significant change for us is the new feature 5 in the 
changelog:

"X[Y] now names non-join columns from i (...) with an i. prefix (...)"

The new naming scheme implies a substantial number of changes in our 
code. Can this feature be considered "stable", i.e. can we already 
migrate our code? Or is there the possibility that the naming scheme 
might change again until the release of 1.9.4?

Thanks,
Christian
