Thoughts on this sort of feature?
I would prefer the syntax
if( (int i = someFunc()) >= 0 )
{
// use i
}
as this matches the already existing assignment expression
syntax if you pull the declaration out of the if expression.
Well you can argue the "if( init ; condition )" syntax matches
"for( init ; condition ; update)", minus the "update" section.
You've just answered your own question:
for (int i = someFunc(); i >= 0; )
{
// use i
break;
}
Yes, it was one of the examples I gave in the first post. Reason
not to use that is, if you forget "break" you are probably going
to have an infinite loop. As well you can't use "else" with a for
statement.
