           Summary: Errors on the Template page of the language
                    specification
           Product: D
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2

These are found on the page:
http://dlang.org/template.html

1) In the spec it says:

Even if template arguments are implicitly converted to the same template
parameter type, they still refer to different instances:

struct TFoo(int x) { }
static assert(is(TFoo!(3) == TFoo!(2 + 1))); // 3 and 2+1 are both 3 of type
int
static assert(!is(TFoo!(3) == TFoo!(3u)));   // 3u and 3 are different types

...but at least according to DMD, TFoo!(3) and TFoo!(3u) refer to the same
type.


2) In the spec it says:

Template arguments not implicitly deduced can have default values:

void Foo(T, U=T*)(T t) { U p; ... }

int x;
Foo(&x);    // T is int, U is int*

...but the last line should be:
Foo(x);    // T is int, U is int*
