This code doesn't work!
------------
template tfunc(fun...) {
    auto tfunc(U)(U r) {
        return r;
    }
}
void bar(T)(T x) {
    // import std.functional; x.tfunc!(unaryFun!"a"); // <- OK
    x.tfunc!(a=>a); // <- NG
}
void test() {
    bar(uint.init);
}
void main() {
    bar(int.init);
}
------------
RESULT
------------
$ dmd -run main
Error: function main.bar!(uint).bar.tfunc!(__lambda2).tfunc!(int).tfunc is a
nested function and cannot be accessed from main.bar!(int).bar

fix Issue 8575 - Lambda expression causes compilation error with template
function

Template lambda is an expression, so we should keep FuncExp until actually
starting instantiation of passed template instance.

 Fixed for D2


Lambda literal is only in D2. So we should mark this "RESOLVED FIXED".

Heh, the online documentation disagrees, but you're right.
