I get an error when I try to find that letter is among alphabet.
onlineapp.d(13): Error: template
`std.algorithm.searching.findAmong` cannot deduce function from
argument types `!()(immutable(char), immutable(string))`,
candidates are:

If you replace the findAmong call with
`[letter].findAmong(alphabet)`, this works.
Consider:
```d
import std;
void main() {
import std.ascii : alphabet = letters;
string wordExample = "Book.";
foreach (letter; wordExample)

It returns a zero-length array that, because it's not null, is
true. That's wh

`if (([letter].findAmong(alphabet)).length)`
I'd like to use some method on the `letter` instead of []
And `.length` does not make a lot of sense when rea

I tried out .canFind method, and to test it I removed the
letter 'o' from the Alphabet.
Weirdly enough .canFind method still found 'o' letter among the

I think nested foreach loops are more readable.
