Instead of naming these operations, we could use '+' and '-', with semantics:

     >>> b = 'world'
     >>> c = 'hello world'

     # Some values between the variables.
     >>> a + b == c
     True
     >>> a == c - b
     True
     >>> b = -a + c
     True

Summary: using '-' for trimming works well for postfixes, badly for prefixes, and not at all for infixes. Clever but not too practical since trimming prefixes seems to be more common than trimming postfixes.
