http://dlang.org/spec/template.html#TemplateTupleParameter
Apart from the obvious need for changing the references to tuples to alias sequences (for which I'm working on a PR), my question: Both the above page and http://dlang.org/phobos/std_meta.html refer to "slicing" alias sequences. In D slicing means just creating another reference to the same memory as the sliced object. Given that AliasSeq-s cannot be written to[*], it's not possible for me to test whether it's actually sliced or a new AliasSeq with the same elements is created. Otherwise I could do something like this: alias A = [int, 2, symbol]; alias B = A[1 .. $]; alias C = A[0 .. $ - 1]; A[1] = 3; // not possible static assert(B[0] == 3 && C[1] == 3); So out of curiosity I'd like to know how this is implemented in the compiler: as really a slice or a copy? (Posting this to D and not learn since it relates to compiler internals.) -- Shriramana Sharma, Penguin #395953
