Does a statement after defer: get called when breaking iteration early?

Question

For example when iterating over lines of a file using the lines iterator from the standard library, does the file get closed correctly if I break the iteration early using break?

Answer 1

As the documentation says:

var f = open("numbers.txt")
defer: close(f)
f.write "abc"
f.write "def"

Gets translated into:

var f = open("numbers.txt")
try:
  f.write "abc"
  f.write "def"
finally:
  close(f)

So the close(f) will be always called after the try code, even if it includes a break.
