Static Array with negative index results in a strange error-message

[Dgame via Digitalmars-d-learn]

char[-1] c;

results in
Error: char[18446744073709551615LU] size 1 * 18446744073709551615 
exceeds 0x7fffffff size limit for static array

Should we fix that? A negative index should be IMO detected 
sooner/with a cleaner error message.
