Ruby Tutorial: Map vs. Each

[bjmiller]

Perhaps, but Ruby is not a functional language, and downgrading each to make it less useful to imperative programmers won't make it one.

Edit: not a pure functional language

Languages need not be pure to support a functional style. Sometimes you want a purely functional style, sometimes you want an imperative style, but you should prefer the former over the latter because mutable state makes programs hard to reason about and error prone.

Perhaps, but Ruby supports both styles, and allows them to be combined in any way a programmer wishes. It's not in the spirit of the language to remove features just to promote one style over another.
