	106	FIX ME : fix alloc interface after Ticker Number 214 is resolved, define and add union to S_fill. Then, modify postfix-fill functions to support T * with nmemb, char, and T object of any size. Finally, change alloc_internal.
	107	Or, just follow the instructions below for that.
	108
	109	1. Replace the current forall-block that contains defintions of S_fill and S_realloc with following:
[fd54fef]	110	forall( T & \| sized(T) ) {
[ceb7db8]	111	union U_fill { char c; T * a; T t; };
[685810e]	112	struct S_fill { char tag; U_fill(T) fill; };
[ceb7db8]	113	struct S_realloc { inline T *; };
	114	}
	115
	116	2. Replace all current postfix-fill functions with following for updated S_fill:
	117	S_fill(T) ?`fill( char a ) { S_fill(T) ret = {'c'}; ret.fill.c = a; return ret; }
	118	S_fill(T) ?`fill( T a ) { S_fill(T) ret = {'t'}; memcpy(&ret.fill.t, &a, sizeof(T)); return ret; }
	119	S_fill(T) ?`fill( T a[], size_t nmemb ) { S_fill(T) ret = {'a', nmemb}; ret.fill.a = a; return ret; }
	120
	121	3. Replace the $alloc_internal function which is outside ttype forall-block with following function:
	122	T * $alloc_internal( void * Resize, T * Realloc, size_t Align, size_t Dim, S_fill(T) Fill) {
	123	T * ptr = NULL;
	124	size_t size = sizeof(T);
