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;
    }
