I think it's still best to "enable" such a style in some cases -- Python's 
syntax is designed to allow formulation of a problem in the most natural 
way.  Sometimes it's more natural to formulate a problem as a recursive 
function than a procedural one, but the current implementation restricts 
this.

I agree that "recursion is the basis of everything" is harmful, but I
think the same belief can apply to "procedularism is the basis of
everything" (why do we have classes, list comprehensions, etc.?).  Some 
things are better formulated in a procedural style, while others are 
better formulated in a recursive style.
