Bug #13012: irb fails to define a method with a reserved-word-ish keyword argument

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.4.0dev (2016-12-07 trunk 57012) [x86_64-darwin14]
• Backport: 2.2: DONE, 2.3: DONE, 2.4: DONTNEED

[matsuda (Akira Matsuda)]

For example

def a(if:) end

is a valid ruby code but this doesn't work on irb.

This seems to be happening for all keywords that are listed in RubyLex::ENINDENT_CLAUSE

ruby-lex.rb: fix for label

• lib/irb/ruby-lex.rb (identify_identifier): treat identifier just
  followed by a colon as a lable. this is not a precise solution
  but enough for the time being. [ruby-core:78526] [Bug #13012]
