[ruby-core:86533] Re: & unary operator for block-proc conversion

Hi Liam,

For general, you can check https://github.com/ko1/rubyhackchallenge (our 
lecture materials for first step Ruby internal hacking. This activity is 
named Ruby Hack Challenge). But they don't explain about "How blcok-proc 
conversion works" because it is a very deep topic.

http://patshaughnessy.net/ruby-under-a-microscope is the best book to 
understand how the internal works. But it is some old (it is based on 
Ruby 2.0). But it will help you the basic of MRI internals (VM).

Now a day, the conversion C-function is `rb_vm_bh_to_procval()` in 
vm_insnhelper.c, but to read this function, you need to understand how 
to represent these data structures. They are very complicated.
