0x0dea / daily_programmer_210e.rb
Created April 13, 2015 22:19
This script uses 237,267 anonymous functions (and, essentially, only those functions) to determine that 17 and 10 have four bits in common.
$fns = 0
# Automatically curry all functions for slightly greater legibility.
# Keep track of how many functions end up getting created (for laughs).
# Get to use the fancy symbol everywhere.
def λ
$fns += 1
proc.curry
