Bug #7706: Lazy#zip should not call `lazy`

• Status: Closed
• Assignee: marcandre (Marc-Andre Lafortune)
• Target version: 2.0.0
• ruby -v: r38825

[marcandre (Marc-Andre Lafortune)]

Current implementation of Lazy#zip has problems:

1. calls lazy when this is not excepted, necessary nor documented. Any reason to not call each instead?

2. calls lazy without checking previously for type:

   [1].lazy.zip(42) # =>NoMethodError: undefined method `lazy' for 42:Fixnum

   expected same as [1].zip(42), i.e. a TypeError

3. inefficient in the case where all arguments are arrays

I'll address these when I get a chance. I don't understand why lazy is called instead of each though. Anyone?
