It's a legitimate concern, and there's no right response to it. My point
is that the argument is weak and caving to it would be a mistake. In
essence Nick claims he can't be bothered to change:
if (long_expression_one)
if (long_expression_two)
if (long_expression_three)
statement
with
if ((long_expression_one)
&& (long_expression_two)
&& (long_expression_three))
statement
which adds a grand total of two parens.
I often write code like this:
if(auto p = getSome())
if(auto parent = p.getParent())
if(auto uncle = parent.getBrother())
uncle.doSome();
This cannot be translated into a conjunction of conditions without
having to specify declarators before. I would not like to lose that
possiblity.
I'm not so sure about the dangling else issue. I don't want to be
pampered all the time, but I have to admit to have run into that issue, too.
