But hope springs eternal!  Of course this aphorism explains neatly every 
problem I've ever run across while using a computer.  But maybe someday 
they'll make a computer that undertands *me*!

Makes the code easier to read too."

I think that's the real lesson.  I try to do that, but I'll be trying even 
harder now.


If they'd thought of it long ago, S and R could have been written so that 
"<-" had to be followed by a space or an error would result.  That might 
have been a good idea, but it's too late now.  So we just have to not make 
mistakes.  I'm working on it.
