If you can afford a dependency on rlang, `rlang::zap_srcref()` deals
with this. It's recursive over expression vectors, calls (including
calls to `function` and their hidden srcref arg), and function
objects. It's implemented in C for efficiency as we found it to be a
bottleneck in some
Thanks Martin.
Following Duncan's advice as well as some textual input, I have put a proposed
Rd file for
optim on a fork of the R code at
https://github.com/nashjc/r/blob/master/src/library/stats/man/optim.Rd
This has the diffs given below from the github master. The suggested changes

Hello,
In the current R-devel @ is S3 generic, so we can do things like - for example
- use it to extract matrix rows by name:
.S3method("@", "mm", function(object, name) object[name,])
m <- structure(matrix(rnorm(20), ncol=2), dimnames=list(paste0("row",
1:10), paste("col", 1:2)),
