Random DMD Facts.
I've decided to document everything here that I come across. On this page you'll see a truly random assortment of facts about DMD Internals. (Which may be outdated by the time of reading)
1) Detecting a default initialization of a class:
class C {}; auto c = new C()
Will be represented as a `NewExp` To get the function that is being called you need to look at the member `member` If that `FuncDeclaration` is null, that is a default initialization.
2) Null statements stand for empty statements
Usually in DMD null node represent that something has not been resolved yet.
However a new which contains an optional statement (Such as {})
will represent a missing statement as null.
