Why does 6.times.map work in ruby 1.8.7 but not 1.8.6
- by Lee
The following code snippet works fine in 1.8.7 on Mac OS X, but not in 1.8.6 on Ubuntu. Why? Is there a workaround?
Works in 1.8.7:
$ ruby --version
ruby 1.8.7 (2009-06-08 patchlevel 173) [universal-darwin10.0]
ltredgate15:eegl leem$ irb
>> 6.times.map {'foo'}
=> ["foo", "foo", "foo", "foo", "foo", "foo"]
>>
But not in 1.8.6:
# ruby --version
ruby 1.8.6 (2008-08-11 patchlevel 287) [i686-linux]
Ruby Enterprise Edition 20090610
# irb
irb(main):001:0> 6.times.map {'foo'}
LocalJumpError: no block given
from (irb):1:in `times'
from (irb):1
irb(main):002:0>
Why is there a difference? What's the workaround for 1.8.6?
