Even in english this isn’t true, for example dots can appear inside a sentence for multiple reasons (a decimal number, an abbreviation, a quotation, three dots, etc, etc), which would make you split it into more than one piece.

What you need here is not the stability in memory (i.e. of pointers, which you lose when you recreate an object) but instead just the stability of an identifier (e.g. the index into a list).
