Well, not really, though it is an interesting idea.  I think that it might 
just add to the confusion that some people already seem to be experiencing 
on this issue.  On that note, I was assuming that people writing `if(x = y)' 
and meaning `if(x == y)' were just making some mechanical error.  It has 
been brought to my attention, however, that the problem may be caused by a 
confusion of the `=' symbol in C with that of some other language, by 
someone who regularly programs in multiple languages.  In such a case the 
bug would be much harder to find.  While I could take a hard line and say 
that anyone programming in C should know what the operators are, I will ask 
a question instead: For those of you who regularly program in several 
languages, how big a problem is this, and would changing `=' to `:=' really 
fix it?  If it turns out to be a significant problem, maybe it could be 
changed.  I think there is a newsgroup `cfutures' that could discuss the 
change.  Mr. Bernstein's suggestion could be considered as well.
