Hi all, sorry for the very simple question, but I'm looking at 
the "among" function in std.comparison:

https://dlang.org/phobos/std_algorithm_comparison.html#among

If I have a string array:

string[] fruit = ["apple", "pear", "strawberry"];

How do I use "among" to see if "apple" is present.  E.g.  I want 
to do this:

if ("apple".among(fruit))

However that wont compile - I'm missing something fundamental in 
my knowledge.

It seems fruit has to be a Tuple?  Is there a way to use a string 
array instead?

among doesn't take an array, but rather a list of arguments:

"bar".among("foo", "bar", "baz")


For searching in an array, you can use canFind:

if(fruit.canFind("apple"))
