Project Euler Problem 45 This is mostly unoptimized and terribly slow. Takes about 40 seconds on my i5-3320M.
-- Project Euler Problem 45
--
-- Triangle, pentagonal, hexagonal
--
-- Triangle, pentagonal, and hexagonal numbers are generated by the following formulae:
-- Triangle Tn=n(n+1)/2 1, 3, 6, 10, 15, ...
-- Pentagonal Pn=n(3n−1)/2 1, 5, 12, 22, 35, ...
-- Hexagonal Hn=n(2n−1) 1, 6, 15, 28, 45, ...
--
-- It can be verified that T285 = P165 = H143 = 40755.

-- Project Euler Problem 36
-- Double-base palindromes
--
-- The decimal number, 585 = 1001001001 base 2 (binary), is palindromic in both bases.
--
-- Find the sum of all numbers, less than one million, which are palindromic in
-- base 10 and base 2.
--
-- (Please note that the palindromic number, in either base, may not include
-- leading zeros.)

Project Euler problem 37 in Haskell
-- Project Euler Problem 37
-- The number 3797 has an interesting property. Being prime itself, it is
-- possible to continuously remove digits from left to right, and remain prime
-- at each stage: 3797, 797, 97, and 7. Similarly we can work from right to
-- left: 3797, 379, 37, and 3.
--
-- Find the sum of the only eleven primes that are both truncatable from left
-- to right and right to left.
--
-- NOTE: 2, 3, 5, and 7 are not considered to be truncatable primes.
