I can't think of anything other than:

  blk.call_but_collapse_surplus_arguments_into_the_final_parameter_as_an_array

:)
  
This concept does not, AFAIK, map to any short name.  Nor is it
endorsed by any theory in computer science.  I'd be interested to know
the origin and purpose of "yield semantics", but I doubt they derive
from some "best practice".

My conclusion: yield semantics are unlikely to ever be known as
anything other than yield semantics :)  It has nothing to do with
yielding; it's just, as you said, historical.
