But I did spend some time with a post-doc working on the Discussion of her manuscript. I had forgotten that last time we worked on it we tore the existing Discussion into shreds and came up with a new organization. So this morning I was discouraged to see that we had improved our Discussion out of existence, but our new organization is so much better that we soon had at least half of the text in place.
On the Perl side of things, a very helpful commenter (Neil) pointed out that finding the missing/extraneous curly bracket would have been easy if we were using an editor that highlights and validates syntax. We're using an editor called 'mi'. It lets us specify that our text is Perl, and uses colours to distinguish between different kinds of text (comments are red, text to be printed is grey, functions are green, operators are sort of purplish, 'while's and 'if's and 'my's are blue), but it doesn't sort out hierarchical stuff like the levels of brackets, and the levels of indentation keep going to hell (possibly my own fault). I'd love to hear about a better Perl editor for Macs, if any reader knows of one.
