:~$ qri =~
---------------------------- Multiple choices:

     Gem::Dependency#=~, Gem::Platform#=~, Object#=~,
     REXML::Light::Node#=~, RegAnd#=~, RegOr#=~, Regexp#=~, String#=~

:~$ qri object#=~
--------------------------------Object#=~
     obj =~ other => false
--------------------------------
     Pattern Match---Overridden by descendents (notably Regexp and
     String) to provide meaningful pattern-match semantics.

so you probably want,

/foo/ =~ nil

=> nil

and if failing is divine, try #match

/foo/.match nil

=> nil

nil.match /foo/
