While what you're saying is true, exponentiation not being
runnable at compile-time is a defect and I would assume a
regression. I'll file a bug report. FWIW when trying to run the
following with DMD v2.077.1 I get:
```
void main(string[] args)
{
import std.stdio;
enum e = (1.0 / 255.0f) ^^ (1 / 2.2f);
writeln("e = ", e);
}
```

FWIW, if the exponent is an integer, I don't get an error.
