We may even disallow all implicit conversions that lose a significant amount of
information:
double => float
real => float
(I think C# requires such casts).
And maybe even (but this is less handy, so I am not sure): real => double
------------------------
Even long => real sometimes loses a little information:
import std.stdio: writeln;
void main() {
real r = long.min;
writeln(r, " ", cast(long)r, " ", long.max-cast(long)r);
}
But for now I'm not interested in regulating long => real implicit casts.
