Runtime constant definitions

[Lars Kyllingstad]

Hi,

I'm trying to define a couple of constants that I want to be computed at 
run time. I have written the following code:

---

/// Square root of real-number precision.
final real REAL_EPSILON_SQRT;

/// Cube root of real-number precision.
final real REAL_EPSILON_CBRT;


static this()
{
     REAL_EPSILON_SQRT = sqrt(real.epsilon);
     REAL_EPSILON_CBRT = cbrt(real.epsilon);
}

---

Compiling this, I get the errors

scid/core.d:21: Error: cannot modify final variable 'REAL_EPSILON_SQRT'
scid/core.d:22: Error: cannot modify final variable 'REAL_EPSILON_CBRT'

where the lines 21 and 22 are the ones inside the curly braces. What's 
wrong?


Thanks,
Lars
