This makes no sense to me, The first element in the array at index zero should be 42, not zero? Is this intentional or a typo?

I really do not like this syntax $:13.37 because its inconsistent with slicing. $ is the length of the array, Its nonsensical it looks like your trying to write 13.37 into the 11th element of a 10 long array.

import std : writeln;
void main()
{
    string foo = "hello";
    // This will be an out of bounds error.
    writeln(foo[$]);
    // This should also be an out of bounds error
    // Otherwise your adding a one off special meaning for `$`.
    float[10] bar = [$:4.14];

    // This will slice out the full array & print hello.
    writeln(foo[0..$]);
    // This will write 4.14 into the full array.
    // If you know how slicing works this should be intuitive.
    float[10] baz = [0..$:4.14];
