template warg(R)
{
    enum bool warg = false;
}

void blarg()
{
    int r = void;
    auto s = r ~ "xxx";
    bool bbb = warg!(typeof(s));
}

bug.d(11): Error: incompatible types for ((r) ~ ("xxx")): 'int' and 'string'
bug.d(12): Error: expression warg!(_error_) is void and has no value

It shouldn't be trying to instantiate the template at all.

Another consequence of this is that CTFE can get called on a ScopeExp, which
doesn't make sense (and the ScopeExp is an invalid template). This happens for
example when compiling std.range with -debug -unittest.
