Bug #1376: inline symbols/fixnums in a case expression do not honor an overwritten #=== method

• Status: Closed
• Assignee: ko1 (Koichi Sasada)

=begin
The case expression in Ruby 1.9 does not seem to honor the fact that Symbol#=== could have been overwritten prior to the expression.

An example with both Ruby 1.8 and Ruby 1.9:

$ ruby -e "class Symbol; def ===(o); p 42; true; end; end; case :foo; when :foo; end"
42

$ ruby19 -e "class Symbol; def ===(o); p 42; true; end; end; case :foo; when :foo; end"
$

The same problem seems to exist with fixnums as well.

In case of variable, it works.

class Symbol
def ===(o)
p 42
true
end
end

this works

a = :foo
case :foo
when a
p 'a'
end

this dosen't work

case :foo
when :foo
p 'b'
end
