Hello, I have a problem I can't even understand with the code
For the first I realized that an UDA can be a type too, and come
up with this:
template getUDA(alias a, U){
enum u = q{ getUDAs!(a, U)[$-1] };
static if(hasUDA!(a, U)
Hello, I have a problem I can't even understand with the code
below:

import std.stdio, std.range, std.algorithm, std.traits, std.meta;
struct UNIFORM{ string name; }
struct A{
int i1;
@UNIFORM() int i2;
@UNIFORM("fuzz") int i3;
@UNIFORM int i4;
}

Try UDAs instead of a map:

Good idea, thx! I already using UDA's for range and measurement
units.

Wow, string mixin can process comma separated list, I gotta
remember this, thanks!

The spec explicitly says it's not legal: "Aliases cannot be
used for expressions" (Item 10):

Hello,
I have a 2 level nested struct structure with nice descriptive
field names.
And I thought it will be easy to alias those identifierLists with
a few letter names and do some calculations on them.
But I'm having an error.
struct A{
struct B{ int c; }
B b;
auto f(){
alias d = b

I think what you want is `std.meta.staticMap`. Something like
this:

Hi,
I was able to reach all the fields in a subclass using foreach
and BaseClassesTuple, but is there a way to do this using
functional programming primitives, but in compile time for tuples?
private template FieldNameTuple2(T) {
enum FieldNameTuple2 = BaseClassesTuple!T.map!(S =>

Is there a way to the following thing in a class instead of a

Hello, anyone can help me make this better?
The functionality I want to achieve is: While serializing the
fields of a struct, I want it to check the @STORED UDA on every
field. If there is no fields are marked with @STORED, that means
every field must be serialized. Otherwise only the marked o
