I'm all for a bump of version number from 5 to 7, provided it doesn't cause big problems and adds something. As Karen Etheridge states:
”We haven't really gotten seriously into the discussion yet of what perl 7 will include. All that's happened so far is one person made a premature announcement of what they wanted, (parts of) the community objected, and we backed up and created a governance process.
I certainly want perl 7 to be more than what has been so far ascribed to it, to make the major version number change truly worthwhile."
other comments in that thread elaborate on this problem, as do posts on p5p.
