You missed the point: there is no "Ruby version". They are the
same thing.
foreach to me is a redundant obfuscation
How can it be redundant? It's got the same elements the same
number of times.
rofl.copter.each |lol|

end
foreach(lol; rofl.copter)

Same elements, just reordered.
I don't know about the each() method itself. I've never written
one, but I suspect it is virtually identical to opApply too.
It's pretty similar. Say I reimplement the "each" method of the Array
class then it could look like this:
class Array
def each
i = 0
while i < length
yield self[i]
i += 1
end
end
end
"yield" will call the block that is passed to the method call.
