It seems to be triggered by a Phobos unittest. Still, I can't reproduce it with your test case. Which DMD version are you using? -Lars

Ah, found the problem. dmd a b -unittest works. dmd b a -unittest does not. Ok, now I can reproduce it too, with 2.046. This just makes it even more clear that it is a DMD bug, not a Phobos one. I've been running into a lot of these order-of-compilation bugs lately. :( -Lars

Tuple to tuple conversion
Sounds stupid, don't it? 123456789012345678901234567890123456789012345678901234567890123456789012 Carrying in my hat my trusty foo, a std.typecons.Tuple!(float), I want to use it as a parameter to a function taking non-tuple parameters, i.e. a single float. foo.tupleof gives me an unwieldy conglomerate of tuple((Tuple!(float))._field_field_0,(Tuple!(float))._0). First, I'm not sure what all of this means, second I'm completely sure it does not mean what I want. foo.field seems much more close to what I want, returning a nice and clean (float) when I ask for it. However, doing so in the context of being a function parameter yields other problems, in the form of: src\phobos\std\typecons.d(424): Error: static assert (is(Tuple!(string,float) == Tuple!(string,float))) is false src\phobos\std\typecons.d(413):instantiated from here: Tuple!(string,float) src\phobos\std\typecons.d(423):instantiated from here: slice!(1,3) problem.d(15):3 recursive instantiations from here: Tuple!(float) Especially interesting might be line 424, as that assert ought to be true in most cases. I guess what I'm asking for here is, is there a way to do what I want? -- Simen
