From the section on expression tuples:
"""
It can be used to create an array literal:
alias Tuple!(3, 7, 6) AT;
...
int[] a = [AT]; // same as [3,7,6]
"""
I was surprised to read this, as I tried that very thing just yesterday and it didn't work. I have now investigated further. My findings:
-----
import std.stdio;
alias Tuple!(1,2,3) AT;
void main() {
int[] foo_dyn_local = [AT]; // works
int[3] foo_static_local = [AT]; // works
writefln(foo_dyn_local);
writefln(foo_static_local);
// writefln(foo_dyn_global);
// writefln(foo_static_global);
}
// Error: cannot implicitly convert expression (tuple1,2,3)
// of type (int, int, int) to int
//int[] foo_dyn_global = [AT];
// Error: cannot implicitly convert expression (tuple1,2,3)
// of type (int, int, int) to int
//int[3] foo_static_global = [AT];

Why does this only work at function scope?
