Don't use return statement in call block

return statement in call block returns from surrounding method instead of returning from call block.

Following code snippet describes it with example.

def function1(&block)

callback_result = yield('value1', 'value2')

puts "call block returned: #{callback_result}"

end

def function2()

function1() do |param1, param2|
puts "block implementation of function2 with param1 => #{param1} & param2 => #{param2}"
return "#{param1} changed. #{param2} changed."
end

puts "next line after calling function1"

return "function2 returned"
end


def function3()

function1() do |param1, param2|
puts "block implementation of function3 with param1 => #{param1} & param2 => #{param2}"
"#{param1} changed. #{param2} changed."
end

puts "next line after calling function1"

return "function3 returned"
end

output of function2() is

block implementation of function2 with param1 => value1 & param2 => value2
"value1 changed. value2 changed."

Output of function3() is

block implementation of function3 with param1 => value1 & param2 => value2
call block returned: value1 changed. value2 changed.
next line after calling function1
"function3 returned"
