I don't get this pattern. Is it documented somewhere ?
Full pattern looks like this:
template foo(T...)
if (T.length == 1)
This is a way to workaround D template argument limitation - you
can't have any parameter that accepts both types and symbols
(`alias T` and `T` at once) other than variadic parameter. Limit
variadic length to 1 and you emulate such "accepts anything"
parameter.
