Bug 12914 – std.typecons.alignForSize will not accept immutable names argument

// The following code compiles and works as expected. import std.typecons; struct X {} struct Y {} alias FieldTypes = TypeTuple!(X,Y); struct A { mixin(alignForSize!(FieldTypes)(["x","y"])); } // However, the following fails to compile, giving the message: // "Error: alignForSize (string[] names...) is not callable using argument types (immutable(char[][]))" immutable string[] fieldNames = ["x", "y"]; struct B { mixin(alignForSize!(FieldTypes)(fieldNames)); } // I think the problem is due to alignForSize having the incorrect signature: // string alignForSize(E...)(string[] names...); // If I'm not mistaken it should be something like: // pure string alignForSize(E...)(in string[] names...); // This is my first posted bug and I'm no D guru, so hopefully I'm not simply confused about something. Thanks!
