The real world has a whole lot of "ifs" in it. "If it's this hardware rev, do this." "If the employee is a manager with more than five reports, they need to take this training." "If the account is more than 30 days delinquent, then send a second notice. If it's more than 60 days delinquent, call. If it's more than 90 days, begin collections."

Because the real world is like that, there is no possible programming language that is going to prevent the need for "if". Users may think they don't care about that, but the requirements are full of "if".

Loops you don't need to code today - if you don't need too precise a control over execution. If you need real control, you probably need to write the loop instead of just using a comprehension.

Data storage schemas: As databases scale, efficiency of storage start to add up to real money. The user may not care, but the finance people care a great deal.
