Pattern: Use of return inside begin..end

Issue: -

Description

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.

Examples

# 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
