Research direction
Start by reading src/assign.c around alloccolwrapper() and its neighbouring functions, then review how R_RegisterCCallable() is currently used. Determine whether exposing alloccolwrapper() is the appropriate scope and whether a tester PR can validate the callable interface. Done means the export proposal has consensus and its external use is tested.

Description
It is lovely that some C level functionality will be exported in the next release!
@davzim @lsilvest and myself just wrote up a small piece on the Rcpp Gallery on creating a data.table object from C(++).
It would be lovely to also get to do the setalloccol() from that level. I looked into its source, and Calloccolwrapper() to alloccolwrapper() and its neighbouring functions in src/assign.c
Would it be possible to export these? Maybe starting with alloccolwrapper()? I'd be happy to put a tester PR together if there is a consensus view that this may have merit. Now that R_RegisterCCallable() is called it is simple enough to add a second entry.
