Not sure I care about this one, it's an error in the code that I gave to SiB. Essentially, it should have printed the error that Ruby prints here rather than evaluating it. But do I really want to try to figure out whether the user has void value violation in their code as I walk the AST? Prob not but maybe.

$ cat f8.rb
a next

$ ruby f8.rb
f8.rb:1: void value expression

$ bin/seeing_is_believing f8.rb
a next

# !> f8.rb:1: void value expression
# !> $SiB.record_result(:inspect, 1, (a next))
# !>                                         ^
# !> /Users/josh/code/seeing_is_believing/lib/seeing_is_believing/event_stream/producer.rb:86:in `record_exception': undefined method `size' for nil:NilClass (NoMethodError)
