Dear R-Core Team, I found an unexpected behaviour in utils::removeSource (also present in r-devel as of today). --- # create a function which accepts NULL argument foo <- function(x, y) { if (is.null(y)) y <- "default foo" attr(x, "foo") <- y x } # create a function which utilizes 'foo' testSrc <- function() { x &...

Dear R-devel, In a package of mine, I use removeSource on expression objects in order to make expressions that are semantically the same serialize to the same byte sequences: https://github.com/cran/depcache/blob/854d68a/R/fixup.R#L8-L34 Today I learned that expressions containing function definitions also contain the source references for the functi...

...pplications (IIRC caching). I'd be happy to upstream this in base if R core is interested.

...same inputs. I've checked source code in digest package hoping to get around this issue (for example serialize(..., refhook = ...)). However, my workaround did not work. It seems that the markers to the objects are different even if I used `refhook` to force srcref to be the same. I also tried `removeSource` and `rlang::zap_srcref`. None of them works directly on nested environments with multiple functions. I wonder how hard it would be to have options to discard source when serializing R objects? Currently my analyses heavily depend on digest function to generate file caches and automatically sc...
