It doesn't work as intuitive as you'd expect:
void main()
{
int x = 256;

You can build dmd with the `./build.d` script or `make

You can build dmd with the `./build.d` script or `make -f

Hello, I have the next code (minimized with DustMite):
struct Tup(T...)
{
bool opEquals() {
foreach (i; T)
static if (__traits(compiles, mixin("new
InputRangeObject11261!(abs_class)")))
msg;
}
}

Very nice! What about proposing this for inclusion into
`std.typecons` or `std.meta`?

Well, first out of curiosity. But there are also other reasons:
I've got a large immutable array. Without CTFE I'd use some php
