Why don't pointers and .sizeof work with typetuples
----
import std.typetuple;
void main(){
TypeTuple!(int,char)* test;
TypeTuple!(long,int).sizeof;
}
----
$ rdmd test
test.d(3): Error: can't have pointer to (int, char)
test.d(4): Error: no property 'sizeof' for tuple '(long, int)'
Failed: ["dmd", "-v", "-o-", "test.d", "-I."]I know they can be wrapped in structs but shouldn't this work in the first place.
