import std.meta : AliasSeq;
AliasSeq!(float) a;
auto b = cast(int)a;
static assert(is(typeof(b[0]) == float));
The above assert passes. I would argue the cast is nonsensical and should result in a compilation failure, though an argument could be presented for casting all elements to int. Neither of these happen with the current compiler.
