If you allow all block lambdas to have early returns with "ret", then
this:
fn f() {
for int::range(1, 10) |i| {
ret i;

}
Has a very different meaning from:
fn f() {
int::range(1, 10) |i| {
ret i;
}
}
IMHO this is likely to be pretty confusing.
Fair enough, I can see where you are coming from.
Also, eliminating "do" makes this ambiguous:
spawn() || {
...
}
Is ambiguous with bitwise-or. This is also ambiguous:
spawn || {
...
}
As I understand it, given point 2 of the proposal, the above code would
not be valid. Instead it would look like:
spawn(|| {
...
});
Is that correct? If so, would the semantics of the directly above be
identical to:
do spawn {
...
}
?
