Other options would be the use of similar symbols as exponent

In order to prevent preprocessing from destroying the side information of the limit operator, you can replace +/-0 by +/- something symbolic, which can be replaced by 0 after the limit operation.

One could also define a unit '+ and a unit '-, which could receive a special translation. Currently, this fails because Maxima does not accept operator symbols in names.
