Hello everyone. =A0I'm a newbie with a question whose answer is probabl= y
obvious, but I'm too thickheaded to figure it out, so here goes...

We can say "cba".reverse or x.reverse and get "cba". Al= so x.upcase or
"abc".upcase and get "ABC".

So it's pretty clear that x and "abc" are objects, because we= 're able to
use =A0methods to send messages to them.

But when I do x.print or "abc".print it throws an error. =A0I hav= e to use
print x or print "abc", which seems to violate the "least su= rprise"
principle and causes sleep deprivation in clueless newbies like me.
Also,
things like print x.upcase.reverse just drive me up a wall. =A0Why not
x.upcase.reverse.print?

Can anyone help?
