Most of them can be accomplished by other methods; that's why I didn't
prepare splice, which behavior is sort of hard for me to use.

# make a basic sandwich
sandwich = %w( bread bologna bread )
p sandwich

# change our mind, go for club sandwich instead.
sandwich.[1,1] = %w( chicken lettuce bread bacon mayo )
p sandwich

# hmmm. hold the mayo and butter the bread, please
sandwich[1,0] = ['butter']
p sandwich

sandwich[-2,1] = ['butter']
p sandwich

# time for lunch
mouth = sandwich.slice!(0..-1)
p mouth
p sandwich

# try to cause indigestion
# we can't do this directly; but I'm not sure how this is important
#gullet = mouth.splice( -99999, 256, ['vinegar', 'baking soda'])
#puts mouth.inspect

# we can't do this directly; but I'm not sure how this is important
#gullet = mouth.splice( 256, -9, ['zotz'] )
#puts mouth.inspect

mouth[1,256] = ['pickles', 'ice cream']
p mouth
