Is there any huge difference as regards performance and memory

An associative array is a rather more complex data structure,
so if you don't need it, use some

Yes, they are much faster. Normal array indexing is equivalent
to *(myArray.ptr + index) plus an optional bounds check,
whereas associative array indexing is a much, much larger job.
Why were you using associative arrays in the fi

Has this happened to anyone. I think I came across this before.
Say I wanna split a string that contains hyphens. If I use
std.algorithm.splitter I end up with empty elements for each
hyphen, e.g.:
auto word = "bla-bla";
auto parts = appender!(string[]);
w.splitter('-').copy(parts);
// parts.data.length == 3 ["bla", "", "bla"]
This is not ideal for my purp
