Hello Simon,

This is something which could be clarified in the documentation.
Thanks, I'll fix the docs.
btw, is it possible to fix the behavior? it will reduce overhead for
storing small strings
It would be possible yes. When the RTS needs to know the size of the
array in words it would have to do a calculation, so you'd have to find
all the places in the RTS that do this (probably only a handful, as most
of them go through the arr_words_sizeW() inline function).
I don't plan to do this right now. If someone else wants to tackle it
then please go ahead, it'd be a fun afternoon hack.
Cheers,
Simon
