is this correct?
No, that doesn't work if the string = "a"[$..$] for example
Just use
if(s.length && s[0])
instead
just `i

used to C++/C#'s world I cautch myself doing something like this:
if(s !is null && s.length > 0 && s[0] == '/)
then a I remembered the D's way, which length is probably a
function not a property (in the C++/C#'s sense, which needs this
as first parameter, hence s.
