--- Comment #2 from Don <clugd...@yahoo.com.au> 2010-11-10 00:27:33 PST ---
Extra test case (add to the end of the original test case):
---
    void delegate (int) pure nothrow dg = &foo.add!(int);    
    dg(7);
    assert(foo.value == 20);

PATCH: e2ir.c, callfunc(), line 294.  To determine if a function is strongly
pure, you need to look at the function declaration, not just the function type,
since the 'this' parameter isn't part of the type.

    {   /* Do not do "no side effect" calls if a hidden parameter is passed,
         * as the return value is stored through the hidden parameter, which
         * is a side effect.
