Three years ago to the day, a blind Python user described an Emacs
python-mode extension he wrote to deal with this issue:
The primary trick appeared to be the code already in pymode that uses the
status line to indicate which block is being closed by a dedent:
Thus, as I close each block, I hear the block that I am
closing with utterances of the form
"closes block while: i<n"
"closes block def foo: "
I don't know how that could help when just *reading* code, although pymode
has lots of Python-savvy navigation commands ("go to nearest-enclosing def",
etc) that could be hooked to a speech driver.
