Hi! I'm new to dlang but loving it so far! One of my favorite
first things to implement in a new language is an interval
library. In this case I want to submit to a benchmark repo:

If anyone is willing to take a look and give some feedback I'd be
very appreciati

I'm building with LDC. I haven't pulled up a linux box to test
drive gdc yet.

Thanks for taking a look! What is it about Mir Slices that makes
them faster? I hadn't se

I just started following links, sweet blog! Your reason for

To encourage inlining, you could make it an alias parameter
instead of a delegate, something like this:

Mir is fine-tuned for LLVM, pointer magic and SIMD

I'll have to give that a shot for the biofast version of this.
There are other ways of doing this same thing that could very
well benefit from Mir.

But one simple thing to try is to add 'scope' to the callback
parameter, which could potentially save you a GC allocation.
I'm not 100% certain this will make a difference, but since
it's such an easy change it's worth a shot.

Hmm, looks like it's not so much input that's slow, but
*output*. In fact, it looks pretty bad, taking almost as much
time as overlap() does in total!
This makes me think that writing your own output buffer could
be worthwhile. H

For speedups with getting my hands dirty:
- Does writef and company flush on every line? I still haven't
found the source of this.
