Like any programming language, D is not perfect. This page lists some potential problems that have been brought up and debated throughout the language's history. Fixing these is not straight-forward or may not justify breaking backwards-compatibility. As of the moment of writing this, there are no plans for a major revision of D which would allow such breaking changes, but this list may also be useful for other programming languages which wish to learn from D's experience.
Properties
Design of properties has been an oft-discussed topic. This language feature has evolved throughout D's history (e.g. the addition and removal of the -property switch. There are numerous DIPs with proposals on improving the design:

Unicode and ranges
D's ranges currently treat strings in a special way: they present them as a range of code points, thus implicitly performing UTF decoding. Algorithms that do not require working with decoded code points, and which would gain a performance advantage by treating the input as a range of code units (or an array of code units), must incorporate D strings as a special case. This approach complicates the implementation by some degree, and only solves a certain subset of problems for a subset of written languages.
