I am wondering should I always use a comma before using 'such that' or not?
sentence 1 , such that sentence 2.
More clearly, I just wrote the following sentences in order to lighten the point, whereas I normally want to know the general idea of it.
Please leave the kitchen door open [,] such that they can come in from the garden.
It certainly is possible to adapt these new concepts [,] such that they can also handle more complex tasks.
Additionally, I leave out the comma in such sentences.
