Comment (by cactus):

 Hmm. `mkWorkerArgs` looks like quite the rabbit hole... does it make sense
 to figure out the plumbing for that, or is it good enough to just steal
 the basic idea and implement something similar for pattern synonyms that
 ensures there's always at least one argument (a synthetic `()` if need be)
 to pattern synonym wrapper functions returning unboxed values?
