I don't know about everyone else, but I find it *immensely* helpful to write debugging statements without indentation. This makes it so that they stand out from the normal statements among which the debugging statements are inserted. This is the reason I won't even consider using Python.
Just stick "# XXX" comments around your debug code. Many editors automatically highlight XXX so prominently that it's just as easy to spot as unindented code.
Now, all you Python-indentation-style lovers, consider how you would code this kind of Go initializer:
(This declares the variable 'arr' as a slice of slices of ints and initializes the variable.)
You mean, like:
arr = [[1,2,3][4,5,6]]
What's the problem?
