Interesting.. Looks like the compiler does some boundschecking
during compile time. You could circumvent this:
void process(T ...)(string ID, T args) {
if (ID == "I1") { writeln(args.length, "\t", args[0]);
}
static if (T.length > 1) // only add below code if
cond. true
if (ID == "I2") { writeln(args.length, "\t",
args[1]);}
}
Oddly, when leaving out the "static if" statement, the error
still occurs when compiling with "-release" or with
"-boundscheck=off"... I thought those would/should disable
bounds checking at compile time???
Nonono ))
In this case, the bound checks are like interface checking...
or like type checking... As there are different processes
instantiations for different number of args.
I hope this can't be turned off so easily... ))))
Aw, got it. So args is actually a tuple type where accessing
beyond the defined tuple (T) is invalid?
auto a = [1, 2, 4];
// works
pragma(msg, typeof(a[3]));
auto t = tuple(3, 4, 5.3);
// ERROR:
// pragma(msg, typeof(t[3]));
