It looks like the compiler does not see the mixed-in "bar". If
I comment out the definition of "bar" in "FooBar", it compiles
fine. Is this to be considered a bug?
No, it's working as intended: "If the name of a declaration in a
mixin is the same as a declaration in the surrounding scope, the
surrounding declaration overrides the mixin one" --

You can use `alias` to bring the two together:
struct FooBar {
mixin Foo!int f;
alias bar = f.bar;
void bar(ulong d)() {}
}
