The former works while the latter fails. It looks like there's some
manipulation of 'bytes' and 'list' when writefln forces evaluation. My
question is should this happen?

Hello,
I need to test in sequence the bits of an unsigned int (see below more
precision), and move in a tree accordingly. Since there are 2 possible branches
at every step, they are encoded in a [2] array, indexed by bit. I am looking
for the fastest way to get that bit.

Also, My actual need would rather be to move forward. The reason is this
