78995827f7 Remove a couple more unneeded function heads 
The `:do` seems to be accounted for by the implementation. Tests
shouldn't pass if this is needed.

43f832d4e3 Clarify List.delete example 
Using numbers in the example tends to confuse the learner about what the
purpose of the second argument to delete is. They might think it's an
index value. This is further exacerbated by the example's value at index
2 being 2. To clear this up, change the example to use non-numeric
values.

c6f2738fc7 Refactor error expansion to locate errors in koan module 
The previous strategy wasn't robust enough to detect typos in function
calls. For example, if you misremembered String.duplicate/2 as
String.repeat/2 the koan runner would hang and have to be restarted.
This is because the stacktrace for an error like that doesn't have line
numbers. To avoid the problem, we detect the first pieces of the
stracktrace that is in the koan module. I can't decide if that's a
perfect solution, but it seemed to work in my testing. Hoping to get
other's feedback.

43c2bbdd71 Show left and right hand values when equality fails 
For assertions that contain function calls, displaying just the
expression is not helpful. For e.g.

  Assertion failed
  String.upcase("foo") == "Foo"

The learner is given no extra information to help them learn. Sure they
might consult the documentation (and should!), but perhaps a better
experience would be for us to inform the learner about the values it
encountered.

  Assertion failed
  String.upcase("foo") == "Foo"
  left:  "FOO"
  right: "Foo"

Learner: 💡 ah hah! it upcases the whole string! 💫

f9a7f7016c Prefer function output over input 
When learning about the behavior of a function, in general the learning
experience is better when provided with the input and asked for the
output.
