Searching for Elements in Containers

[Nordlöw]

Is there some function similar to std.algorithm.find() which 
returns an element index instead of a range? I guess 0 means no 
hit and 1, 2, 3 means hits at indexes 0, 1, 2 etc.

I want this to avoid having to create ranges ([]) when searching 
for a specific element in std.container.Array.
