[1.9] Symbols are allowed in Range: (:Z..:a).to_a, etc.
-------------------------------------------------------
Key: JRUBY-4194
URL: http://jira.codehaus.org/browse/JRUBY-4194
Project: JRuby
Issue Type: Bug
Components: Ruby 1.9, RubySpec
Affects Versions: JRuby 1.5
Reporter: Hiro Asari
Assignee: Thomas E Enebo
In 1.9, Symbols are allowed in Range, and they should be treated special.
{noformat}
surfboard:~$ ruby19 -ve 'p (:Z..:a).to_a'
ruby 1.9.2dev (2009-10-31 trunk 25580) [x86_64-darwin10.0.0]
-e:1: warning: (...) interpreted as grouped expression
[:Z, :"[", :"\\", :"]", :^, :_, :`, :a]
{noformat}
The symbols that appear above are those between 'Z' and 'a' in the ASCII table.
Right now, in JRuby, (:Z..:a).each (.step, .to_a) go into an infinite loop,
since successive invocation of 'succ' for ':Z' will never get to ':a'.
Also, there is a spec for this in spec/ruby/core/range/to_a_spec.rb.
A question remains whether :Z..:a should behave as above; but that's a question
for MRI, I guess.
