Work only this variant:
```
alias custom = Typedef!int;
custom[] arr = [cast(custom)1,cast(custom)2,cast(custom)3];
```
but this crap

import std.conv;
custom[] arr = [1,2,3].to!(custom[]);

OR

import std.algorithm;
import std.array;

custom[] arr = [1,2,3].map!(x => cast(custom)x).array;


work for me.
