I got so bored writing tutorials I tried this:
A:begin
begin
println "hi";
println "world";
end A
This experiment seems to work. The rules are simple:
1. labelled begin matches labelled end with the same label.
2. begin matches end
3. You can leave out unlabelled end
4. You can NOT leave out labelled end
I got sick of:
for i in X do
for j in X do
for k in X do
do something
done
done
done
especially if that is nested as well. Loops can already be labelled anyhow,
since Felix allows break/continue to have labels to escape multiple
levels of loop. So now you could just write:
X: for ..
for ..
for
something
end X
In fact you could write this:
fun f () {
for i in X do
for j in Y do
something
}
since now unlabelled "done" is optional.
Other syntactic variations are possible... er ..
X: ... /X
if you like XML .. :) {Argg)
This:
X:end
X:done
might work too.
