Hello Simon,

Consequently I expected sizeOfByteArray# to return the same number that I passed in to newByteArray#. But it doesn't - It returned however much it decided to allocate, which on my platform is always a multiple of four bytes.
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
