A code fragment using static foreach
https://forum.dlang.org/thread/jiefcxwqbjzqnmtaz...@forum.dlang.org#post-beruryblsptnunsowjph:40forum.dlang.org
does not compile with the current GDC (GCC 4.9.4 and 5.5.0). I
tried to encapsulate this code into a version block but GDC
still checks the syntax. Is there any more elegant way besides
of using a mixin?:
version (DigitalMars) {
pragma (msg, "DMD");
mixin (`
enum typenames = ["float", "double", "real", "short",
"int", "long"];
static foreach (s; typenames) {
pragma (msg, s);
disp[s] = mixin ("&mymain!" ~ s);
}
`);
}
Are you looking for something like this?
---
static if (__traits(compiles, () { static foreach (i; [0]){} }))
version = supportsStaticForeach;
void main()
{
version(supportsStaticForeach) {
pragma(msg, "Yay, your compiler is new enough.");
}
}

Don't support GDC (or only GDC-master)?
