This little program
const xyz = 123
var foobar:int
echo "hello world"
Run
lives in /tmp/testit.nim. Compiling (on an up-to-date Arch Linux system)
doesn't produce an "unused symbols" hint, despite explicitly turning it on (I
_think_ it's on by default):
dca@franz:/tmp$ nim compile --hint[XDeclaredButNotUsed]:on testit.nim
Hint: used config file '/home/dca/.nim/config/nim.cfg' [Conf]

One issue that may or may not be relevant: trying to install Nim yesterday with
curl https://nim-lang.org/choosenim/init.sh -sSf | sh
failed (twice) with a segfault. So I installed by downloading the tar file and
building manually. The resulting directory is in ~/.nim and I've added
~/.nim/bin to my PATH.
Is the lack of mention of the unused symbols a compiler problem, or am I
missing something?
