Just a couple of thoughts from my phone, which is why I cut out the message: 1. Sub signatures have been prototyped, and quite successfully, on CPAN. The internal interface could be improved, but the core support is there. 2. The docs in perldoc explicitly suggest, going back to at least 5.8.x, which is about all I use for now, that alphabetical characters in prototypes had been banned to allow for this syntax to be added in the future. I agree wholeheartedly on not adding new keywords, but this feels more like filling a gap then adding something new, using a model for the feature that has been successful on CPAN.Thread Previous | Thread Next
