But the whole expression won't.

irb(main):001:0> irb(main):001:0> 5.times {|i| "a"}
=> 5
irb(main):002:0> 5.times {|i| puts "cat"}
cat
cat
cat
cat
cat
=> 5

And puts "cat"  doesn't return "cat"

irb(main):004:0> puts "cat"
cat
=> nil

On the other hand Integer#times is documented to return the integer:

 qri Integer#times
---------------------------------------------------------- Integer#times
     int.times {|i| block }     => int
------------------------------------------------------------------------
