FWIW, the thing I miss sometimes is the equivalent of C's:
while((x = next()) != nil) {
something()
}
In Go you need to do either:
for x = next(); x != nil; x = next() {
something()
}
which duplicates the per-iteration expression, or:
for {
x = next()
if x == nil {
break
}
something()
}
which is 4 lines longer and the invariant is inverted.
A two-part for statement could potentially do that:
for x = next; x != nil {
something()
}
but it's too subtly different from the normal form to be a good language change.
