I am not a English native speaker, so I have a different feeling.
These functions do array_serialisation and array_deseralisation, but
this names are too long. I have not idea about better names - it is
descriptive well (for me) text->array, array->text - and these names
shows very cleanly symmetry between functions. I have to repeat - it
is very clean for not native speaker.
