Here's a little trick I've used when building
a module for various windows functions that
aren't in Walter's windows.d yet.  A number
of structures in the windows API require the
first member to be a UINT with the structure
size in it.  Which can be initialized in the
structure definition like this.

struct MENUITEMINFO
{
  UINT cbSize = MENUITEMINFO.size;
  UINT fMask;
  UINT fType;
  UINT fState;
  UINT wID;
  HMENU hSubMenu;
  HBITMAP hbmpChecked;
  HBITMAP hbmpUnchecked;
  DWORD dwItemData;
  LPTSTR dwTypeData;
  UINT cch;
  HBITMAP hbmpItem;
}

Ok, it's not much of a trick, but simple
things make me happy. :-)

A neat one! Never really thought of the fact that struct members can be initialized... It is also interesting that it can determine size of the struct before it had even been declared.

I love it when neat things like this are discovered!
