I gather that curly braces and do..end are supposed to work the same, why then is this ok

def save_block name, &b
  @blocks ||= {}
  @blocks[name] = b
end

save_block :say_hello do
  puts "hello!"
end

but not this:

save_block :say_hello {
  puts "hello!"
}

=begin
They aren't actually supposed to work the same. do/end and {/} differ in binding precedence. Your code is the equivalent of:

save_block(:say_hello) do
puts "hello!"
end

save_block(:say_hello {
puts "hello!"
})

That's the difference between the two types of block delimiters. Not new, not a bug.
