Bug #11812: Lack of space between colon and % literal causes syntax error

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.3.0preview2 (2015-12-11 trunk 53028) [x86_64-darwin15]
• Backport: 2.1: DONTNEED, 2.2: DONE

[fcheung (Frederick Cheung)]

The following snippet

{tags:%w(a)}

executes fine in ruby 2.2.3, but raises "syntax error, unexpected '%" when run under ruby 2.3.0preview2. When it is changed to

{tags: %w(a)}

Then it parses with ruby 2.3.0preview2 too.
