I am working on a pretty large literate program right now, and am using coderefs in the blocks. I know I can add a -r switch to a code block to remove the labels, but there are /a lot/ of blocks, and I wondered if there was some way to specify a file-wide switch, or a language specific switch? It isn't obvious that is possible, so I thought I would ask.
