How can I get around this?
```
struct Foo(T) {
static foreach (m; __traits(derivedMembers, T)) {
static foreach (i, method; __traits(getOverloads, T, m)) {
static if (is(typeof(method) Params == __parameters)) {
}
}
}
}
```
Error: declaration `Params` is already defined here.
If I recall, there used to be a trick for static foreach using double
braces, but the compiler complains "declaration expected not {".
This is because in D static foreach does not create new scope and all
iterations are executed within the same scope, which leads to the error.
You need to explicitly add the scope:
```
static foreach(..){
static foreach (...) {{ // <-- note double curly braces
...
}} // <-- note double curly braces
}
```
