           Summary: Inout function with lazy inout parameter doesn't
                    compile
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: hsteoh quickfur.ath.cx

Code:

inout(int) func(int x, lazy inout(int) defaultVal) {
        return defaultVal;
}

void main() {
        int x = func(1,2);
        const(int) cx = func(1,2);
}

Compiler error:

test2.d(4): Error: inout on return means inout must be on a parameter as well
for pure  safe inout(int)()
test2.d(8): Error: inout on return means inout must be on a parameter as well
for inout(int)()
test2.d(9): Error: inout on return means inout must be on a parameter as well
for inout(int)()

Clearly, this is wrong, because inout *is* on the second parameter. It's being
masked by the "lazy", as can be proven by removing "lazy" and it will compile.
