can be compiled and run without warning/error
however
echo 1== 0
Run
can be compiled and run as expected, but there is a warning ` Warning: Number
of spaces around '==' is not consistent [Spacing]`
the most strange is that nim refuses to compile
echo 1 ==0
Run
and says
Error: type mismatch: got <int literal(0)>
