I'm making something like an IDE.
The text search function in it is able to search across all user

I thought about filtering the search results by context.
The following contexts are planned already

That was it! Thanks!
Conclusion: This is how to overload cmp()
```d
//this is the only place from where all other modules can see
these std modules

Yes, but in the 40 module project I'm unable to make it work.

Hello,
I try to make an overload group of cmp() functions in my utility
module but everything works well except when I import some 3rd
party module that imports std.algorithm. Then I get an error:

Hello,
I noticed that the LDC2 compiler has an architecture target
called "AMD GCN".
Is there an example code which is in D and generates a working
binary of a hello world kernel.
I tried it, and just failed at the very beginning: How can I
specify __kernel and __global in D?

Thank You!
I will remember that in case of weird errors I can try to help
the compiler with type inference.
Hello,
Somehow it can't reach map and array inside a class field
initializer. If I put that small expression inside a function, it
works. If I encapsulate the initializer expression into a lambda
and evaluate it right away, it also works. Only the nice form
fails.
Why is that?

Hi,
In my framework I just found a dozen of compile time error
handling like:
...else static assert("Invalid type");
This compiles without error. And it was useless for detecting
errors because I forgot the first "false" or "0" parameter.
I think it is because of the weird case of "every s

I don't care whether it is good practice or not. :) The
following is what you meant anyway and seems to work.
I restricted the parameter types to the ones I wanted to use.
And for the standard iota behavior I used a public import.
