UFCS is only supported for module-level functions, as far as I know.

Does DWT is built upon Java's SWT ? I heard that SWT is somewhat slower in windows. Anyhow, what about the easiness of DWT ? Actually, i just want to make GUI for Windows only. I dont need a cross platform GUI. DTW is a translation of swt, I can speak to speed comparisons but I don't think you could apply anything out their related to comparing dfl and dwt. You can write windows only apps in dwt, don't compile for Linux, it uses native drawing. @Jesse Phillips, Thanks a lot. :)

No UFCS with nested functions?
Why does the following not work? It works, if I move the 'prop'
out of 'foo'.
---
struct S {
ubyte[12] bar;
}
bool foo (ref S s)
{
static bool prop(const(ubyte)[] f) {
return f.length > 1;
}
return s.bar[].prop;
}

Thanks!
Using shared memory and thread
Dear, I would like to put a buffer `shared(char[])` into a shared memory ( L2 cache ) and provide a start and end index to multiple thread in order to perform computation on a piece of original buffer. I read doc from std.concurrency, std.parallelism, core.thead (druntime) and vectorization (simd) . But I found any example or unittest which perform such calculus. 1/ So did you have an example somewhere ? 2/ about shared keyword do we ensure that its size is lower than L2 or L3 cache using : ``` core.sys.posix.unistd: sysconf, _SC_LEVEL2_CACHE_SIZE, _SC_LEVEL3_CACHE_SIZE; immutable size_t L2_CACHE_SIZE = cast(size_t) sysconf(_SC_LEVEL2_CACHE_SIZE); immutable size_t L3_CACHE_SIZE = cast(size_t) sysconf(_SC_LEVEL3_CACHE_SIZE); ``` 3/ variable flagged as `shared` does at mean the variable is put into L2 cache ? thanks for your help best regards

Dub and gitsubmodules
Does anyone know a reliable way of having a dub package that contains git submodules and is to be used as a dependency? I am looking for a way to ensure the submodules are initialised before a build.
