this kind of thing doesn't work super well due to the nature of
compile time. My suggestion is to put the checks and the
implementation in separate things.
void foo(T...)() {
static bool checkHelper() {
bool passed;
static foreach(t; T) {
static if(is(t == whatever)) {
passed = false;
}
}
return passed;
}
static assert(checkHelper());
// then foreach to do the rest of it
}
something like that. maybe returning string instead of bool to
have an error message you print out with the static assert.
i don't love this but it is the simplest way I know.
