I'm a D noob so take it with a very big grain of salt, but I
think that expression is wrong already on the level of the
syntax. In your expression x doesn't have any type, neither
explicit nor deduced. I suppose that something like that could
work:
f.Create((auto x) { }, "asdf"); // verbose syntax
cannot deduce arguments compiler error.
Surely D can figure out that T is a string?
If one simply changes this to
public struct Foo(T)
{
public void Create(uint delegate(T) c, T param)
{
}
}
and
Foo!string f;
everything works.
The second parameter is a string so why not infer that T is a
string?
Also, if one does
f.Create((string x) { }, "asdf");
Here x has a type and the definition is syntactically correct.
Then it works. Seems like a blatant limitation in D's type
inferencing system.
