Thanks for your contribution @rileyli. Even though this change seems rather
trivial I would like to discourage these kind of contributions. The problem is
that it does not add much additional value at the cost of introducing subtle
bugs (e.g. variable name clashes). Therefore, I would like to ask you to close
this PR.---
