How can I make something like the following work without
"Error: cannot
append type double to type string[]" ?
T[] some_function(T[] var) {
T[] var2;
double a = 12.34;
string b = "hello";
if(typeof(var).stringof == "double") {
var2 ~= a;
}
if(typeof(var).stringof == "string") {
var2 ~= b;

Use static-if, but you shouldn't use .stringof. Check the
actual type and not the string of the type:
static if(is(typeof(var) == double)) {
var2 ~= a;
}
static if(is(typeof(var) == string)) {
var2 ~= b;
}
Oh, the "static if" ... for compile time evaluation; seems
unintuitive (no?) since data is encountered at run time.
