Hmm, seems I forgot to add std.string, now it works, but words seems not to be an array, at least I cannot access it like an array. words[0][0] leads to

 Error: no [] operator overload for type MapResult!(__lambda1, ByLine!(char, char))

So is is a map? How can I convert all the elements in it to integer and store it in a real array?

I believe it's by using array:
auto words = file.byLine()           // you've all lines in  range
                  .map!(a => a.split).array();

Sorry, I didn't notice the "convert all the elements in it to integer" part.
I think I saw reference to the to! before...that is one way to convert.

auto words = file.byLine()           // you've all lines in range
                   .map!(a => a.split)
		   .map!(a => to!int(a)).array();

import std.file, std.stdio, std.string, std.conv;

void main(){

	auto file = File("text.txt");
	auto numbers = file.byLine()
               .map!(a => a.split)
               .map!(a => to!int(a)).array();
	
	writeln(numbers);
}

ep18.d(7): Error: no property 'map' for type 'ByLine!(char, char)'

Actually, need an extra map I think:

auto word = file.byLine()
                    .map!(a => a.split)
                    .map!(a => map!(a => to!int(a))(a))
                    .array();

And also:
import std.algorithm

Sorry, I should have taken the time to answer properly and fully.

import std.file, std.stdio, std.string, std.conv, std.algorithm;

void main(){

	auto file = File("text.txt");
	auto numbers = file.byLine()
                 .map!(a => a.split)
                 .map!(a => map!(a => to!int(a))(a))
                 .array();
	
	writeln(numbers);
}

Error: no property 'array' for type 'MapResult!(__lambda2, MapResult!(__lambda1, ByLine!(char, char)))'

Still an error.

	import std.algorithm : map;
