what's the difference between a lambda/proc and a block?

BTW it's impossible for a method that receive a blocks to pass it to
another method without turning it into a proc/lambda (using the &
prefixes), so it makes distinctions between lambda/proc and block rather
undesirable, as there are some techniques that rely on passing blocks
around, and can't work if it involves a difference of behaviour between
"real block" and "block that was converted from a proc that was converted
from a block".

So I'm not sure how that exception would work at all, if an exception were
to be applied...
