THIS!  is exactly the reason I posted the original article titled
"...what's the point",  'cuz I thought I was really getting some 
mileage out of this *type*ing in the the language.  I put this code to 
my compiler (THINK C 3.02).... the results were expected.  It took it
without a htich.  I am new to C, however I still have an opinion.  The
"typing" going on here is an illusion at best in my compiler.  Did you
try this in your compiler?  I do understand the positions of the C-gods
when decreeing the new standard to make as few apps break as possible.
But I still don't agree with it. 

I think if this was implemented in the way that is intuitive to me it
would be a very powerful tool.  Oh well...

Yeah right... I wish it was so in my compiler...  :-)
