> In Python I can just move a block around and, if necessary, move it horizontally to the correct level, whereas in bracelang I often have to adjust braces as well, which are outside the moved section and need extra cursor navigation.

Could you clarify; I think adding one/two more line to the block being moved makes this a similar operation. For that matter, the editor can unambiguously figure out the block and do auto-indentation when braces are present.
