We'll have to be careful as we proceed.  Supporting this opcode means that the FTL now supports "have arguments" functions, which means supporting captured variables.  It 's really weird.  I don't know how to explain it other than recommending that you read the code. :-/  And probably talk to Geoff, who was the last one to do things with the semantics of arguments.
