StackableFlash.not_stacked do

flash[:notice] = 'a simple string'  # Use flash as if this gem did not exist
flash[:notice] = ''                 # will overwrite the string above
flash[:notice] # => ''

flash[:notice] # => ['a simple string','another'],
               #    but returned as "a simple string<br/>another" with default config
