I found the following behavior surprising:

library(daff)
example(diff_data)  # creates the "dd" patch

save(dd, file = "patch_loading.Rdata")
load("patch_loading.Rdata")

dd
## Error in context_eval(join(src), private$context) : 
##  Context has been disposed.

Almost all R objects can be safely written to Rdata or RDS files. Is this failure expected behavior?

If this is intended, I can contribute a documentation patch to diff_data and write_diff so people at least know to expect this -- it caught me off guard since R objects are usually self-contained and Rdata/RDS files are a big part of my workflow.
