That it uses a string mixin :P
What Manu is arguing is that if parameter storage classes were
instead proper type qualifiers, then one could trivially
manipulate them with std.meta. And then supposedly there would be
no need to string mixins at all.
I haven't spent the time to actually verify if that's the case
here (perhaps the only need for using a string mixin is to
generate variable names like Param1, Param2, ... ParamN) as is(X
== __parameters) solves the issue with forwarding the whole
parameter list (including storage classes), but in general, this
doesn't scale if you need to do type manipulation with std.meta,
as `alias RefInt = ref int` drops the `ref` storage class and
this breaks everything like staticMap, Filter, etc.
