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 appreciative! Specifically if you have an performance
improvement ideas: https://github.com/sstadick/dgranges/pull/1
Currently my D version is a few seconds slower than the Crystal
version. putting it very solid in third place overall. I'm not
really sure where it's falling behind crystal since `-release`
removes bounds checking. I have not looked at the assembly
between the two, but I suspect that Crystal inlines the
callback and D does not.
I also think there is room for improvement in the IO, as I'm
just using the defaults.
Add to your dub.json the following:
"""
"buildTypes": {
"release": {
"buildOptions": [
"releaseMode",
"inline",
"optimize"
],
"dflags": [
"-boundscheck=off"
]
},
}
"""
dub build --compiler=ldc2 --build=release
Mir Slices instead of standard D arrays are faster. Athough
looking at your code I don't see where you can plug them in. Just
keep in mind.
