Description

Just for consistency

Currently behaves as ( ruby --version: ruby 2.5.0dev (2016-12-28 trunk 57228) [x86_64-darwin16] )

'string'.__send__(:=~, nil) #=> nil
'string'.match(nil)         #=> TypeError: wrong argument type nil (expected Regexp)
'string'.match?(nil)        #=> TypeError: wrong argument type nil (expected Regexp)
:symbol.__send__(:=~, nil)  #=> nil
:symbol.match(nil)          #=> TypeError: wrong argument type nil (expected Regexp)
:symbol.match?(nil)         #=> TypeError: wrong argument type nil (expected Regexp)
/regex/.__send__(:=~, nil)  #=> nil
/regex/.match(nil)          #=> nil
/regex/.match?(nil)         #=> false

Expected to

'string'.__send__(:=~, nil) #=> nil
'string'.match(nil)         #=> nil
'string'.match?(nil)        #=> false
:symbol.__send__(:=~, nil)  #=> nil
:symbol.match(nil)          #=> nil
:symbol.match?(nil)         #=> false
/regex/.__send__(:=~, nil)  #=> nil
/regex/.match(nil)          #=> nil
/regex/.match?(nil)         #=> false
