Hello,
Is there a way to quickly build a hash from the values of an
array?
A one-statement equivalent of:
T[] array_values ;
int[T] hash_values;
hash_values = map!() (array_values) ;
Instead of:
for (v; array_values) {
hash_values[v] = 1;
}
in Perl, that would be:
---
Or, put differently, is there a way to convert values in an
array to keys of hash in one statement ?
Thanks!

std.array.assocArray.

T[] keys;
auto aa = zip(keys, repeat(true)).assocArray;

If I am allowed to misunderstand :) it as a *single* hash from all of
the values, then you can use D's internal hash algorithm for arrays:
import std.stdio;
void main()
{
auto arr
