I see.  So your feature conflicts with C feature "variable which is
initialized at declaration time is always used initialized".

 
That doesn't happen here:
 
  int a = a;
 
gcc (with no extra options) tcc and bcc both put some undefined value in a.
 
gcc won't warn until you say '-Wextra', and then only for:
 
  int a = a + 1;

Well, it is rather easy to see if variable is used within its
own initialization, so practically it is minor gap.  Of course,
there is problem with C standard: IIUC depending on rest of
the code declarations as above are merely undefined behaviour
or even produce unspecified value.  So C compiler is
forbidden to stop compilation are report compile time error.

However, your language has no constrains that C has, so you
could do better.
