One way of changing the code is to use the following but it does not

I'm having difficulty understanding how templates operate as
function parameters.
Say I have this:
struct ArrayTest {
void arrayTest(T) (T arrayT) {
writeln(arrayT);
}
}
unittest {
ArrayTest
);
test.arrayTest!(float, 1)(farray);
Sorry, that should be:
test.arrayTest!(float[], 1)(farray);
In your template declaration, you have declared two template
parameters, T and passing, and one function parameter, arrayT. It
is equivalent to:
template arrayTest(T, int passing) {
void arrayTest(T
to match):
void arrayTest(T, int passing) (T arrayT) { ... }
I get 'cannot deduce function from argument types' errors.
Specifically stating the type of the function doesn't seem to
help:
test.arrayTest(float [])(farray, 1);
There must be a way to mix template and non-template parameters,
right

For regular runtime parameters, there's ParameterTypeTuple. How
would I write an equivalent template for template parameters?
i.e.
void fun(Foo foo, Bar bar)() {}
alias types = CtParameterTypeTuple!fun; //TypeTuple!(Foo

Hi,
in this minified example I try to expand the variadic parmaters of
foo to bar:
import std.typecons;
void foo(T ...)(T args)
{
bar(args.expand);
}
void bar(int i, string s){}
void main()
{
foo(1, a);
}
I got the syntax error: no property 'expand' for type '(int,
string)'

Is there a simple way to get it working?
The simplest: just write `bar(args);` - the variadic arguments
will automatically expand.
