That is an excellent question.
Some items in my list are controversial, the first two have already been 
mentioned.

* C-style declarations
* SFINAE
* \n, \r as a string (free up the backslash character)
* #line (make it a pragma instead)
* Octal (it's not 1952 any more)
* the comma operator (allow in selected places, eg for(; ;++a, ++b)).
* package. In DMD, it's a broken implementation of a broken concept.
* The postincrement and postdecrement operators (make x++, x-- identical 
to ++x, --x, except that it is illegal to use the return value. Allowing 
operator overloading of the postfix operators was a silly hack in C++. 
It's a freedom nobody wants).
* is() expressions (I love what you can do with it, but it's 
unintuitive, and traits is a much better solution)
* .sort for AAs.
* Object.toString(). Encourages bad design. It's not powerful enough to 
be useful.
