(In reply to comment #1)

With the patch in comment #1, this example does not link:
--------------------
void main()
{
    immutable s = "abc";
    auto t = s[0 .. $ - 1];
}
--------------------
% dmd -run test
test.o(.text._Dmain+0x1a): In function `_Dmain':
: undefined reference to `_D4test4mainFZv8__dollarxk'
--------------------

The link error does not occur if the dollar $ is replaced with s.length.

The real cause of the link error may be elsewhere (only $ causes a link
error?), but the patch itself doesn't work anyway.  So I remove the 'patch'
keyword.
