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 ==
Here's a more involved example of what I'm trying to accomplish.
Is there an easier/cleaner way to do this? (This is still a bit
reduced, what I'm actually trying to do is compare whether a
given variadic typetuple passed to opDispatch is implicitly
convertible to one of the parameter
