Ruby ignores the underscore character within integer literals.  Instead of writing

bank_account.deposit(:cash => 1000000)

you can write

bank_account.deposit(:cash => 1_000_000)

which is much easier to read.

When I’m depositing a million at my ATM however, I will a) refactor that constant out of my code and b) probably be blogging from somewhere other than my bedroom/home office =)
