Dear R-devel,
I found this behavior disturbing, if `1 + f()` is called, `sys.call()`
called inside of `f` will return a quoted `f()` with a "srcref" that prints
"1 + f()".
I don't know which one is good but I don't think they can be correct at the
same time.
Here's a reproducible example:
f <- function(){
sc <- sys.call()
print(sc)
attr(sc, "srcref") <- NULL
print(sc)
1
}
f2 <- function() {
1 + f()
}
f()
#> f()
#> f()
#> [1] 1
f2()
#> 1 + f()
#> f()
#> [1] 2
Best,
Antoine
