Comments on: Ruby, Python, and references to functions…

The reference to e.g. foo()? Object#send takes a Symbol or a String; you don’t have to do anything special.

I’m not sure I’m answering the right question, though, as I don’t really understand the python code. Are blocks maybe a better answer to what you’re looking for?

def bar (baz, &quux)
puts baz
yeild baz
end

bar(“Weeble”) { |wobble| puts “#{wobble} falls down”}

=> “Weeble\nWeeble falls down\n”

To some extent, but I’d also like to know how to do it in within the current namespace, as you can with nested functions within a method in Python, and it’s the case statement’s power. You’ve described the invocation, which is fine; how do I get the reference?

I think that Ruby’s “You don’t need parentheses to trigger a method” has poisoned Ruby’s headaround.

Are you looking for something like
class MyClass
def foo
end
def bar
end
def baz
end
def whichparam(parameter)
if param=’quux’
return self.send(:foo,parameter)
…..
end
…
