Today I just realized that in DMD optimize flag does not imply

settings and recompiler, expecting to see speedups in my code

Really simple question:
how do I get the compiler-generated hash function for a given
type?
For example:
Struct S
{
int i;
}
can be used in an associative array. That means the compiler
generates a "toHash" function. Is there any simple way to call it
directly?

You can just write
