~ would still be the unique default. @ would require a place (because there's no placement without a place). Just because C++ uses the same operator for regular allocation and for placement doesn't mean we have to do the same. As it's been pointed out already, C++'s use of `new` for placement is kind of quite strange, since it doesn't actually allocate anything.
As for "too punctuation heavy", why the hate on punctuation? Operators have a long history of use in programming languages to great effect. I don't get why operators are now suddenly bad. User-overloadable operators are contentious, certainly, but this isn't an overloadable operator. -Kevin On Dec 2, 2013, at 11:38 AM, Patrick Walton <pwal...@mozilla.com> wrote: > Besides, unless you remove the unique default (which I think would be too > verbose) the default allocator reduces to a pointer sigil. > > Patrick Walton <pwal...@mozilla.com> wrote: > Still too punctuation heavy. > > Kevin Ballard <ke...@sb.org> wrote: > What do you mean?
