Global calling handlers

[HenrikBengtsson]

Funny.

FYI, in R (>= 4.0.0), you can use globalCallingHandlers() to "subscribe" to conditions without having to use withCallingHandlers(). In other words, you can capture and generate your output everywhere.

Gist,

globalCallingHandlers(warning = function(w) {
  message("Woo, careful there: ", conditionMessage(w))
})

and

> as.integer("a")
Woo, careful there: NAs introduced by coercion
[1] NA
Warning message:
NAs introduced by coercion

Thank you @HenrikBengtsson, I did not know that!

I don't know if wrapping all messages would be considered too intrusive, seeing how much real estate the alamak messages take up on screen. But the point of this package is not to be taken seriously/used daily...

I will definitely give your suggestion a try and maybe let the user turn these warnings on or off with a call.
