TMath::Sort :: warning if n < array size

Hi! I was wondering if would be useful (for me it would because i just had some headaches because of this) to have a warning in case that either (this arguments related to [1]):
1. n < sizeof(index)/sizeof(index[0])
or
2. sizeof(index) < sizeof(a)

and definitely an error (if it is needed..) for n > sizeof(a)

Thanks,
Adrian
