Thanks for the help to everyone. It seems a common thing to want
to check an array as one may not know the variables at compile
time. Not that it's more than a few lines to do in D. But in
terms of language adoption, small frictions can have large
consequences over time. (Modern people don't have much patience
or sticking power even if viewed rationally the ROI makes these
things trivial. That's also because in a corporate environment
management are not always patient when somebody tries something
new and not yet mainstream). Making the standard library easy
with no sharp edges might have a high payoff over time.
How would one add this note about needing to pass a tuple not an
array to the docs or wiki ? For docs, clone and submit a pull
request? How about wiki?

In D there is a feature that allows a function to accept
both an array of items and items,
yes - it is funny there is not an overloading that accepts
arrays
I meant this D feature:
void foo(T)(T[] items...) {
import std.stdio;
items.writeln;
}
void main() {
foo("red", "green", "blue");
foo(["red", "green", "blue"]);
auto a = ["red", "green", "blue"];
foo(a);
}
