Subject: [ruby-core:44753] [ruby-trunk - Bug #6378][Open] irb incorrectly considers line incomplete when parenthesis are excluded


Issue #6378 has been reported by devans (Daniel Evans).

----------------------------------------
Bug #6378: irb incorrectly considers line incomplete when parenthesis are excluded
https://bugs.ruby-lang.org/issues/6378

Author: devans (Daniel Evans)
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin11.2.0]


Steps to reproduce:

start irb
attempt to execute the following line:
[1,2,3].reduce :+

Expected:
a result of `=> 6` should be printed and a new line should be available

Actual:
The result is not printed and the shell indicates more lines are expected

irb(main):001:0> [1,2,3].reduce :+
irb(main):002:0*

Workaround:
add parenthesis to the method call:
[1,2,3].reduce(:+)

Notes:
The line is executed, as evidenced by changing the symbol to represent a message to which FixNum does not respond, such as :_ after which the error message will be printed immediately.

This is also reproducible in ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux]

irb versions tested:
irb 0.9.6(09/06/30)
irb 0.9.5(05/04/13)
