Miika - lot of thanks. In .y mind, this is a major improvement.
Also, want to suggest taking a nother look into the semnatic. I agreed
inrange should include the low and high, similar to the gcc extensions) ..
operator, the SQL in operator, perl .. operator, etc.
There is another use common use case: creating a variable that can be used
to index an array. With the inrange:
Double a[MAX_ELEM];
Int ia __attr__((inrange(0, (sizeof(a)/sizeof(a[0]))) ;
One trivial solution will be to define a macro
#define array_index(a) int __attr__((inrange(0, (sizeof(a)/sizeof(a[0])))
And then we can do:
Array_index(a) ia;
which I think is very cool.
