Here is the TLDR version:

<sevenseacat> rubycasts_io_: welcome back.
...
<rickjamesthethir> I have this dictionary and i need to do 2 things. separate into words/sequences and then check to make sure that if a sequence is a duplicate then it never gets outputted in the final output
...
<rubycasts_io_> rickjamesthethir, looks like a job for each_cons :D
<rickjamesthethir> problem is this dictionary is 25,000 words. It's super slow to run an array.each {|x| *searching for duplicate in the same big array* }
<rubycasts_io_> rickjamesthethir, use ruby 2+ and use .lazy
...

1. Controller actions will not expose more than one instance variable
2. Views are used in the context of a controller, they use instance variables
3. Partials are meant to be sharable (multi controllers) so they should only use local variables
