Variable interpolation in strings with ${...} (doc bug 53614)

Looking to fix a doc bug report or two this morning, I came across http://bugs.php.net/53614 referring to the ${...} interpolation syntax. I recall when I first started with PHP, this pretty much had equal status with {$...}, but has fallen away in the documentation to the extent that there's now only a single isolated example of it, with no descriptive text at all. I was really surprised at how low this syntax has fallen, with even one @php.net responder being surprised that it worked at all. So: - AFAIR, this usage has not been deprecated - is that correct? - If not, should the manual make more prominent mention of it? - ... and if so how? A passing mention? A few examples? Or given full equality? - Or should even the one mention be removed and the whole thing just quietly dropped? I think, given the current situation, I'd be inclined to just drop the one passing example and have done with it, but I don't think I have the right to make such a decision unilaterally. However, I'm more than happy to implement whatever the consensus decides. Cheers!
