The methods package ?cbind2 includes the instruction to use via
methods:::bind_activation(TRUE). This changes the default definition of
cbind globally, disrupting proper evaluation in packages not using
cbind2. Is cbind2 a hold-over from a time when ... could not be used for
dispatch? What is a safe way for a package to use cbind2?
This came up in the context of complex package dependencies in
Bioconductor, as detailed in this thread (sorry for the html).
