So I was thinking of some sort of syntax like this:
if(int i = someFunc(); i >= 0)

// use i

Thoughts on this sort of feature?
I'd prefer a new variant of `with`:
----
with (int i = someFunc()) if (i >= 0)
{
// use i
}
----
It's slightly more verbose, but the meaning is clearer
(arguable). It extends automatically to other control
structures like `switch`.
I wouldn't have this new `with (declaration)` have the magic
lookup rules of the existing `with (expression)`. It would be
a simpler tool that I'd probably use more than the existing
`with`.
I really prefer this over if. This just made sense, just at a
glance
Me too.
Would also allow
with(char c = foo()) switch(x)
{
// use c
}
so no need to switch over the new declared variable, but still
beeing able to use it there
