Right around the time I get used to using values(GR) all over the place... and, an excellent opportunity to improve R's Unicode support, squandered! ;-) As long as things work right for SummarizedExperiments and their coercions to/from other common data structures, I'm certainly not going to complain. I'm not sure how I feel about having urged Hervé and Martin to compromise their principles about this, but it will make some peoples' lives a lot easier. Not least, mine, as I try to get examples and documentation completed for the 'regulatoR' package I've been working on lately. Having seen the logic behind your original design decisions, I understand why you were reluctant to do this. If it turns out that we have demanded "enough rope to shoot ourself in the foot", well, we asked for it! So, thank you, quite a lot, for including something that could well be as dangerous as it is handy.
