inject's pathological case...

[thufir]

# example program to illustrate inject num_ary = [10,37,27,398,273,28]

# summing without inject:
without_inject_sum = 0
num_ary.each{|num| without_inject_sum += num}

# summing with inject
with_inject_sum = num_ary.inject{|sum, num| sum + num}

Thank you for the example. I'm not convinced that inject is fantastic,
but certainly it's something I need to understand and this example helps
to illuminates it.

Enumerable#inject is very useful, as long as you don't treat it as
Maslow's hammer and use it in inappropriate ways, such as giving it a
block like in the original posting to this thread.

Ah, the irony: when googling Maslow's hammer:


Microsoft JET Database Engine error '80040e14'

Syntax error (missing operator) in query expression ''http://

ROFL,

I strongly disagree with that statement.

So 7stud, you learned Python and Ruby, decided you prefer Python, and
now hang out on the Ruby Talk mailing list bad mouthing our language?
What's the point, if you don't mind my asking?

The same as for any troll?
