Given this code for CTFE on a string array:
enum E {one, two}
enum string[] fields = [EnumMembers!E].to!(string[]);
string print(string[] fields)
{
string s;
foreach(string field; fields)
{
s ~= field.toUpper ~ ", ";
}
return s;
}
pragma(msg, print(["one", "two"]));
pragma(msg, print(fields));
I am trying to understand why the first pragma produces correct
output but the second one fails in std.string.toUpper (cannot
interpret result ~= c at compile-time)?
