std.digest.hmac already contains a helper function for this:

    hmac!SHA256(data, secret);

The order of arguments is this way to allow chaining with UFCS:

    data.hmac!SHA256(secret);

But it seems the documentation generator can't handle ddoc 
comments in templates, so unfortunately it doesn't appear in the 
documentation.
