OK, just trying to clarify.  You wrote

Somehow I didn't understand what you meant by "syntax for naming
inline blocks" because it did not occur to me that you might be
missing something we actually do have already:

irb(main):001:0> display = ->(x) { puts x }
=> #<Proc:0x201e80c8@(irb):1 (lambda)>
irb(main):002:0> %w[apple banana orange].each &display
apple
banana
orange
=> ["apple", "banana", "orange"]

Now, what is missing?

Kind regards
