This is perhaps a good example of where making your own extensions to
built-in classes, to make your own domain-specific language, is a good idea.
That is, if you're doing it so many times that ,"" is getting hard to type,
then why not shrink 'gsub' too while you're at it?

class String
  def -(re)
    gsub(re,'')
  end
end

a = "some string"
p a - /s/
