Hello,
I have the following code:
string[] list;
string text;
// ...
enum pattern = ctRegex!`^[0-9]+$`;
list = text.split('\n').map!(line => 
line.matchFirst(pattern).hit);

Compiler says that it can't convert result of map function to 
string[]...

The result of `map` is a lazily-evaluated range. To convert it to 
an array, use `std.array.array`:

import std.array: array;
//...
list = text
    .split('\n')
    .map!(line => line.matchFirst(pattern).hit)
    .array;
