I have put up gem minitest_lucid, which elucidates data for certain failed Minitest assertions.

The idea is that a failed assertion for, say, a largish hash can be hard to decipher. So the gem organizes the result to make it easier.

Thus, instead of

-------- expected
+++ actual
@@ -1 +1 @@

we get

So far, treats Hash, Set, and Struct. Coming soon: Array and OpenStruct.
