Bug 14253 – [REG2.067b3] std.traits.ParameterStorageClassTuple gives compiler errors when encountering 'return' functions

Code: import std.traits; struct Foo { ref Foo opAssign(ref Foo rhs) return { return this; } } void main() { alias tup = ParameterStorageClassTuple!(__traits(getOverloads, Foo, "opAssign")[0]); } Output: /Users/kapps/dev/dmd/phobos/std/traits.d(221): Error: key 'j' not found in associative array ['a':cast(FunctionAttribute)1u, 'b':cast(FunctionAttribute)2u, 'c':cast(FunctionAttribute)4u, 'd':cast(FunctionAttribute)8u, 'e':cast(FunctionAttribute)16u, 'f':cast(FunctionAttribute)32u, 'i':cast(FunctionAttribute)64u] /Users/kapps/dev/dmd/phobos/std/traits.d(970): called from here: demangleFunctionAttributes("NcNjKS4test3FooZS4test3Foo") /Users/kapps/dev/dmd/phobos/std/traits.d(993): while looking for match for demangleNextParameter!(__error) /Users/kapps/test.d(8): Error: template instance std.traits.ParameterStorageClassTuple!(opAssign) error instantiating

Other std.traits functions will likely have to be updated to include 'return' as well, such as functionAttributes.
