Three things where pointed out: 1) _ prefix is for placeholders. 2) _ postfix is for keywords. 3) Boost.Phoenix already uses _this (as a placeholder).
In the Boost.Local case _this/this_ is both: 1) A placeholders because it will be "replaced" with the actual object pointer `this`. 2) And obviously a keyword. So what do I do? _this or this_?
It should be this_. The way you're using it is not what I would consider a placeholder. If that were the definition of a placeholder than every reference should be considered a placeholder because the reference gets "replaced" with the actual object, which is absurd.
I might as well be consistent with another Boost library. Plus, if _this is also used in the function declaration (not just the definition) then it really acts as a placeholder. I am only 52% in favor of _this over this_ and I am happy to use the name that the reviewers find more correct.
BTW, I couldn't find Phoenix docs that refer to _this-- does anyone have a link? Is there any other Boost library that uses either _this or this_?
