I have a script in which I want a special case where someone can
input something like a potential or a dispersion relation for use
in physics simulations. I want to clean up the implementation for
users as not every situation requires these. So I wrote a
function with the signature
``` d
void myFunc(Function initialFunc, int timeSteps, double
initialTime, double finalTime, int depth,
double delegate(double, double) source = &nullSource, double
delegate(double, double) spacialDispersion = &identitySource,
bool userOutput = false) {...}
```
where
```d
static double nullSource(double a, double b) {
return(0);
}
static double identitySource(double a, double b) {
return(1.0);
}
```
Is this a good method of implementation? Or should I be doing
this in a completely different way? I am not extremely new to D,
however, I am new to using some of the more unique and advanced
features. Any help or advice is appreciated.
