R: Examples for 'rlang::fn

### ** Examples

# fn_body() is like body() but always returns a block:
fn <- function() do()
body(fn)

do()

fn_body(fn)

{
    do()
}

# It also throws an error when used on a primitive function:
try(fn_body(base::list))

Error in fn_body(base::list) : 
  `fn` must be an R function, not a primitive function.
