As I've noticed that I find myself typing the latter quite often in code I write, it would only be sensible to add the corresponding syntax for the for statement:

for node in tree if node.haschildren(): as syntactic sugar for: for node in tree: if not node.haschildren(): continue

Isn't this the same as

  for node in tree:
      if  node.haschildren():
          <do something with node>

so that all you would save is ':\n' and the extra indents?
