It's a design mistake, but there's a fold function
replacement for reduce that has the right order of arguments. I
don't know why fold isn't in Phobos yet.

For the second, the compiler can tell that if you don't assign
anything more to it then it's immutable. So I'm not sure the
second one is true.

I'm inclined to believe there's some benefit to explicitly using immutable
as Walter has written about it more than once, and it's in D's own
documentation.
While I'm sure the compiler can infer immutability, it probably

just realized I forgot the -release flag on ldmd, sped it up past clang and

gdc and dmd still woefully slow with functional version.
You can also find dramatic differences in C++ performance from one C++ compiler
to another.
weaselcat:
Why does reduce! take the seed as its first parameter btw? It
sort of messes up function chaining.
It's a design mistake, but there's a fold function replacement
for reduce that has the right order of arguments. I don't know

Could you elaborate on the difference between D's
templates/mixins and Nim's macros/type classes?
I'd suggest you read the available documentation on each feature;
for example Nim's user defined type classes are described here

Are there proofs of percentage of bugs caused by incorrectly mutating

Hi all,
i'll like to share my project for building the bindings for QML
in both D and Nim programming languages.
The project is young and it's not complete, however at the
current state slots, signals and properties can be exposed to QML
from D. So a pure databound application can be created
