Catenation with a here-doc obviously:^) (since left-shifting a string isn't legal?);
Would be ambiguous, were it not that then you have a constant in a void context, which is rarely ever useful.
Once you remove the void context as in
it would be ambiguous, but I think that being able to use a number as a here-doc delimiter is as bad as the long deprecated (and now illegal) practice of using a space for that purpose. I always assumed (without ever having had cause to actually check until now) that here-doc delimiters followed the same naming rules as labels. I now see that is untrue, but I can't think of a good reason why it shouldn't be made so. That would remove that ambiguity.
At the end of the day, personally, I'll probably be quite happy to accept '_' or '~' (or any other syntax the powers that be decide upon) for catenation, but 'simple' abuttment seems almost logical (to me), and I was exploring the idea to see what effect it might have on the rest of the current perl syntax. I don't yet see anything that would be a problem that I wouldn't be happy to change to accomodate it, but I don't use most of the more esoteric constructs that it might conflict with, and have relatively little history with the language which means that I am open to possible changes that those with ingrained habits would rail against.
I have no expectation that any of my meanderings are going to influence anything one way or the other, but when I see something that raises a queston in my mind that I can't resolve by a little playing around or research, I am of the habit of asking the question of those with better experience than I. That's my prefered way to assimilate new knowledge. It seems a shame that in some quarters at least, this practice is seen as bad. Not you I might add.
Okay you lot, get your wings on the left, halos on the right. It's one size fits all, and "No!", you can't have a different color.
