This is getting way off topic. I wasn't suggesting that gsubfn, which
does a lot more than this simple
example, as the implementation.
I was pointing out that the replace function idea can be extended to
sub and gsub and showing what
it would do.

That's an interesting example, as it's conceptually similar to what
Pavel is proposing, but structurally different. gsubfn() is more
complicated than a simple switch in the body of the function, and
wouldn't work well as an anonymous function.
Multiple dispatch can nicely encompass both of these
This could be extended to sub and gsub as well which gsubfn in the
gusbfn package already does:
library(gsubfn)
gsubfn("^..", toupper, c("abc", "xyz"))
## [1] "ABc" "XYz"

This approach hardly makes for concise or readable code.

Dear All,
Currently, list= in base::replace(x, list, value) has to be an index
vector. For me, at least, the most common use case is for list= to be
some simple property of elements of x, e.g.,
x <- c(1,2,NA,3)
replace(x, is.na(x), 0)
