Clean-cut, thank you!
It's very clear to me...
```d
import std;
void main()
{
alias fp = char function() @system;
enum DNA : char
{
timin = 'T',
sitozin = 'C',
guanin = 'G',
adenin = 'A'
}
fp getDNA = () => uniform!"[]"(DNA.min,
DNA.max);
enum n = 30;
auto genes = generate!getDNA.take(n).array;
auto unique = genes.uniq.array;
// AAAACATCATGGTAGGCCTTTCATGCGCTA
assert(unique.length < n, "no repeat");
unique.writeln; // ACATCATGTAGCTCATGCGCTA
}
```
