You can really only pass a single type tuple to a template, but you can work around it by passing a length and then comparing two parts of a combined tuple. For instance: import std.stdio; import std.typetuple; void compare(uint LEN, TL ...) () { writefln("%s", is(TL[0 .. LEN] == TL[LEN .. $])); } void main() { alias TypeTuple!(int, double, char[]) tupleA; alias TypeTuple!(int, double, char[]) tupleB; alias TypeTuple!(int, double, char*) tupleC; compare!(tupleA.length, tupleA, tupleB); compare!(tupleA.length, tupleA, tupleC); } will output "true" then "false."
