Fixes #73

@Bisaloo feel free to have a look as it was you who kindly raised the Issue but otherwise fairly confident that it's OK to just go ahead and merge.

Thanks!

Could you please:

• Edit the documentation to highlight that this argument is deprecated.

I also want to take a moment to think about argument order. I don't know if this argument should stay in this position, as it would imply that all the following arguments have to be named. OTOH, if we move it and someone specified it by position in an old script, it will erroneously be passed to id.column.

Tricky one. Perhaps keep where it is for now (not breaking existing codes) and remove in 0.4.0 given that people have been warned?

@Bisaloo any further thoughts? If not I’ll go ahead with this:

Yes, seems like the least worse option. It'll be slightly more annoying for users but cannot generate any unexpected behaviour.

Just a note that a strict semantic versioning adherence would probably warrant a jump to 1.0.0 to remove this argument.
