 Without patch:
 "(eval):1:in `block in <main>': "
 ""
 ["(eval)", 1]
 ["eval_test.rb", 14]
 
 With patch:
 "(eval):1:in `block in <main>': "
 "(eval):1:in `block in <main>': "
 ["(eval)", 1]
 ["(eval)", 1]
 
 Knowing the line of an error inside eval is useful. Passing a binding
 shouldn't discard that information. Present behavior is even wrong:
 there's no line 10 in this file.
