From my point of view, this coding style is fundamentally *wrong*:
- it makes assumptions on the internal data representation,
- and it prevents the compiler from making any optimisation from the
fact that elements of built-in lists are immutable (and if the
compilers makes some optimisations from that fact, then it's not only
the style but the program that is wrong).
