How do I get names of regex captures during iteration? Populate AAs with captures?

Is there a way to get the name of a named capture when iterating over captures from a regular expression match? I've looked at the std.regex code and it seems like "no" to my eyes, but I wonder if others here have... a way. My original problem is this: I need to populate an associative

Alignment of struct containing SIMD field - GDC

struct vec_struct { alias field this; bool b; int8 field; } In this code when you look at the generated x64 code output by GDC it seems to be doing a nice job, because it has got the offset right for the 256-bit YMM 'field' correct. Does D automatically propagate the

Building a project with CMAKE

I'm using CMAKE to build my project. With https://github.com/dcarp/cmake-d this works almost. The only thing I do not manage to get working is running cmake in release mode. When I use -DCMAKE_BUILD_TYPE=Release I get some linker errors, which I do not get, when compiling manually. (In both
