Array remove 1 item? (std.container)

[Damian]

Hi, I've got the jist of using most of std.container.Array, but
I can't seem to remove a single item, I understand I must remove
a range.

Array!int arr;
arr.insert([1, 2, 3, 4, 5]);

So now how would I remove lets say the number 3 from my array in 
the most efficient way? which would leave me with [1, 2, 4, 5] ??

For reference I'm using an Array to replace a C++ std::vector..
