class RuboCop::Cop::Lint::NoReturnInBeginEndBlocks

Checks for the presence of a ‘return` inside a `begin..end` block in assignment contexts. In this situation, the `return` will result in an exit from the current method, possibly leading to unexpected behavior.

@example

# bad
@some_variable ||= begin
  return some_value if some_condition_is_met

  do_something
end

# good
@some_variable ||= begin
  if some_condition_is_met
    some_value
  else
    do_something
  end
end

# good
some_variable = if some_condition_is_met
                  return if another_condition_is_met

                  some_value
                else
                  do_something
                end
