I think, as many seem to be picking up, that tooling is critical for blind programmers and is secondary to how the language is designed. No matter how the language is represented in text, it can be made accessible with the right tooling. Often, however, this doesn't exist. This is why Python is quite polarizing for blind programmers, some love its simplicity and readability and others find the whitespace trips them up. But I think this is a function of what tools blind programmers land on to use Python...and probably also how much residual vision the programmer has. Remember that only 10% or so of blind people are totally blind.
