Re: Quick question on readability

I like:

var1 = ( var2 = var3 );

and I hate:

var1 = var2 = var3;

I think the first version makes it much clearer that var1 is set to the
value of an expression, whereas the second version could be taken
(incorrectly) to mean that var1 and var2 both take the value of var3.

 
Err ... I just realized that my original example should have included:

var1 = (eval var2 = var3), to set var1 and var2 to the value of var3. This 
is probably not nearly as readable as the logical expression case above. 
This doesn't come up often, but today I have a case where I have two 
groups of about six fields where each group should have the same values 
(ie group1.var1 = group2.var1, group1.var2 = group2.var2, ...).  They are 
part of a file record, so using a template DS is not entirely 
straightforward.  I guess this is where the idea of different operators 
for assignment and equivalency would be handy.
