Never used gobject but at a first glance it looks more like a workaround for missing functionality in programming language.

With type checking I mean for example these variables:
  enum {red, green, blue} color;
  enum {right, middle, left} alignment;
  ssize_t fd;
  typedef int angle_type;
  angle_type angle;

Unless their is an explicit cast. Assigning a color to an assignment variable or the opposite should trigger an error at compile time. Assigning an angle to a size or should trigger an error at compile time ... It works for struct and pointer for struct but not simple variables.

It should not be to hard to fix in compiler and I can't come up with any real disadvantages.
