Backport #7408: Assigned but unused warning cancelled by symbol

• Status: Closed
• Assignee: usa (Usaku NAKAMURA)

[agrimm (Andrew Grimm)]

If there is a symbol with the same name as an unused local variable, there is no "assigned but unused variable"

=begin
# no_warning.rb
def no_warning
foo = 1
{:foo => 1}
end

def has_warning
  foo = 1
  {:bar => 1}
end

$ ruby -v
ruby 2.0.0dev (2012-11-18) [x86_64-darwin10.8.0]
$ ruby -w no_warning.rb
no_warning.rb:8: warning: assigned but unused variable - foo

=end
