It gives an error when the exclamation mark is removed, I have no
objections. But typing long instead of char also gives an error!
```d
void main()
{
alias T = char;
import std.traits;
foreach(useableType; AllImplicitConversionTargets!(ulong))
{ /* Except for four: long, float, double, real.
The approval.//*/
assert(!is(T == useableType));
}
// No errors!
}
```
