Block statement

Example:

var found = false
block myblock:
  for i in 0..3:
    for j in 0..3:
      if a[j][i] == 7:
        found = true
        break myblock # leave the block, in this case both for-loops
echo found

The block statement is a means to group statements to a (named) block. Inside the block, the break statement is allowed to leave the block immediately. A break statement can contain a name of a surrounding block to specify which block is to leave.
