mixin template Foo(alias a){ alias Foo=a; }
pragma(msg, Foo!2); // error
template Bar(alias a){ alias Bar=a; }
pragma(msg, Bar!2); // ok
Perhaps I was unclear. What I meant:
What does 'mixin template' do that 'template' does not?
Where would I use 'mixin template'?
As far as I can tell, 'mixin template' does nothing new;
'template' is sufficient. Thus, 'mixin template' seems like
pointless extra syntax.
As I said before, this page http://dlang.org/template-mixin.html
could have replaced all instances of 'mixin template' with
'template' and it would compile (I tested all examples) and run
the same (perhaps not true? I tested about half).
Even the example in TDPL on page 284 works the same when I
replace 'mixin template' with 'template': (this is my slightly
modified version) http://dpaste.dzfl.pl/b582c899fc3f
