I was thinking recently about how I struggled with how to write
code without global variables when learning Erlang.  "How the hell
can you live without globals?" I asked.  It reminded me of learning
the C language.  "How the hell can you live without GOTOs?"(*) I
asked having only ever programmed in BASIC.  I've never used either
and no longer see any reason to do so.

(*) C does have a goto but you're told not to use it just as you're
    told not to use the process dictionary.
