I am "trying" to write a function that takes an array of items,

I tried it with
if( __traits( compiles, A.length ) )
as well. But compiler doesn't match it.
writeln("Max Length: ", maxLength( ["foo", "123456789"] ));
Compilers says it cannot deduce function from argument types ...
I do not want to check whether the type "A" is string, char[],
etc. As long as it has length (please do not put me into
ranges, library functions etc as much as possible), I want the
function to accept it.
iirc there's a hasLength trait in std.traits e.g. static
assert(hasLength!int[])
