Hi.
If we call gets(), the returned string is copied to a special variable $_
Do we have such things for getc(), too?

No, implicit global variables are evil. I'd rather remove $_ in the
future.

I use global variables for golfing only.. :slight_smile: but please don't remove $_!

I _never_ use $_ in any 'def'ed method but I use it in
_every_ '-ne'/'-pe' oneliner. Please keep it.

This is probably a good argument for removing the variable. :wink:

As both a dedicated Rubyist, and an astronomically high-handicap USGA
member, I'm all for getting rid of both $_ AND golfing from Ruby.
Golf is for getting away from the computer. <G>
