can anybody tell me why
struct S
{
int x;
alias x this;
}
void test()
{
S s;
s = 8; // this works
S s = 8 // but this does not?

Hi, I have a simple program with just one line (below). I've
compiled on Windows using
dmd -ms32coff app.d
and have had LINKCMD set to lld-link, but get the following
errors. Is lld-link only for 64-bit compiles (-m64 is the only
one that gives no errors)
lld-link: error: /safeseh: app.obj

The following code results in the static assert in the
constructor being triggered, even though I would have thought no
constructor would have been called. I know that there is an easy
fix for this (move the static if outside the constructor), but it
still seems like it doesn't make sense.
"doesn't work" isn't very helpful. Are you seeing compiler
errors? Linker errors? Runtime errors? Please describe your
problem.
Solved my problem alone : wrong signatures with functions ;)
and this reply isn't very helpful.
