Currently they accept a variable number of arguments instead.

@newStackCall got removed in 71b7f4b

@syscall0
The code is still in the compiler which is why I included it.

It's a low-priority experimental feature which is currently broken in practice on most architectures, but could work in theory.

Whether it makes it into the lang spec or not will be decided before 1.0
