using RubyTapas episode 070 "break" as inspiration, try an on-the-fly version of the technique... which unfortunately doesn't work...

gistfile1.txt

names = Proc.new do |&blk|
  blk.call("Ylva")
  blk.call("Brighid")
end

names.call do |name|
  puts name
end

When I run this, here's the error:

"undefined method `names' for main:Object (NoMethodError)"

since names is a Proc, not a method, you need to do names.call ...

Yeh I tried that also previously. Unfortunately, then the yield calls starting on line 2 result in this error:

"no block given (yield) (LocalJumpError)"

So I decided to search a bit, and found this:

I have now updated the code to a version that works. Not sure if I'll use it, but glad to understand the different pieces involved better. Thanks again.
