there are 3 related problems:

1. it is possible to declare function without specifying return type.

pure foo () {}
pure foo () {}
pure nothrow foo () {}

should be: pure nothrow void foo () {}

2. pure is not enforced when return type is omitted

int bar  = 3;
pure foo () { bar = 42; }

void main ()
{
    writeln (bar); // writes 3
    foo ();
    writeln (bar); // writes 42
}

3. nothrow is not enforced when return type is omitted

nothrow foo () { throw new Exception (""); }

void main ()
{
    foo (); // throws exception
}

Points 2 and 3 were fixed in DMD svn 736.

Point 1 remains, though I don't think it can ever cause problems. Changing title and downgrading to minor.

Original bug title: "pure and nothrow are not enforced when function has no return type specified"
