Hi!
This is kind of bug report/question.
I'm running Ubuntu 12.04 (x64), DMD v2.064.2 and have the
following code:
T identity(T)(T e) { return e; }
struct S(alias Func)
{
void call()
{
import std.stdio;
writeln(Func("string").length);
}
}
static struct S1
{
alias S!(identity) A1;
//alias S!(x => x) A2;
alias S!(function string (string e) { return e; }) A3;
}
void main()
{
S1.A1.init.call();
S1.A3.init.call();
}
The main complaint is that function literal is somehow broken in
that case. The output of the program is
6
4527264
For some reason, length in the second case is wrong.
Another question (which I believe is reasonable) is that I cannot
use the (x => x) syntax for function literal (the commented alias
A2). The compilation error is:
tmp.d(15): Error: delegate tmp.S1.__lambda4!string.__lambda4
function literals cannot be class members
tmp.d(8): Error: template instance tmp.S1.__lambda4!string error
instantiating
tmp.d(15): instantiated from here: S!((x) => x)
tmp.d(8): Error: this for __lambda4 needs to be type S1 not type
S!((x) => x)
I assume, compiler infers the type of the literal to be delegate,
but it's clearly not the case, since I don't need no context here.
I appreciate any comments.
