Summary|template specialization not |implicit conversions don't

|if"? |parameter specialization
Original title: 'template specialization not working because of "static if"?'
It's not because of 'static if'. This shows the same problem:
template pow10(long n){
const long pow10=7;
}
template pow10(long n:0){
const long pow10=1;
}
static assert(pow10!(0) == 1);
It will compile if you put
static assert(pow10!(0L) == 1);
It seems that the compiler requires template value specialisations have to
exactly match both type and value, but I don't see that in the spec anywhere.
Probably a bug. It's certainly pretty annoying.
