# nim c -d:release --opt:size guessing_game.nim
# the resultant binary is 62 kBytes

import random, strutils

# init random seed
randomize()
# this should be inclusive
let secret = rand(0..100)

stdout.write "Guess a number: "

var guess: int

# the ;guess below turns the assignment into an expression
# iow, this gives us the equivalent of the Python := walrus operator
