Hi Gabriel,
thanks for your reply - it does solve the problem of my toy function,
but does come with some other problems though.
a) as.list(f)[[1]] yields an expression, not a function. In order to
go the route you are suggesting, I would more likely use "deparse" in
order to get the original back

Holger,
For me (see session info) using
digest(as.list(f))
gets around this problem.

Hi Luke,
Ah - I see - thank you! This at least points me to a way on how to
"fix" this. I tried setting the srcref attribute to NULL, but the hash
value is still different and so is the serialization. So this looks
like it is one difference, but not all of them
Even if all differences were identi
Add
attributes(testfun)
and you will see where the two functions differ.

also depends on the hash-value of the function that is being ca
