R unary operator overload: risks?

Question

In my continuing quest to avoid using parentheses for some simple commands, I wrote up the following operator to create a new graphics window. My question is: am I at risk of \

Answer 1

with

makeActiveBinding

you can replace ls() by e.g LS w/o need of unary operators

Answer 2

I executed "!" = function(a){stop("'NOT' is used")} and executed the replications function, which uses the ! operator, and this worked fine. So it looks like it is safe to override "!".

Still you probably want to use classes, which you can do as follows:

# Create your object and set the class
A = 42
class(A) = c("my_class")

# override ! for my_class
"!.my_class" = function(v){ 
  cat("Do wathever you want here. Argument =",v,"\n")
}

# Test ! on A
!A
