Because the language lacks goto, breaking out of a nested loop is quite unreadable:
var done = false
for y in 1..10
for x in 1..10
if my_array[x + y * 10] == 0
done = true
break
if done
break
Therefore, I think that named blocks should be introduced:
block loops
for y in 1..10
for x in 1..10
if my_array[x + y * 10] == 0
break @loops
Reasoning behind the syntax:
Prefixed declarations are better than infixed, because they're easier to parse and don't require backtracking.
Thus, block <name> and break @<name> instead of <name>: and break <name>
block should be an expression, thus one should be able to return a value out of a block.
I'm still not sure about the syntax here. break @loops -1 looks maybe just a little weird? Especially when combined with some more complex expression like break @loops x + y * 2
Maybe introduce a with keyword between the label and the result expression: break @loops with x + y * 2
On the other hand, the @label already separates the label name from the expression, especially if it's highlighted differently from normal expressions in editors.
