This reverts commit 17c47958.

Turns out decorator performs some magic to support kwargs better than we do.

On windows the temp file cannot be opened a second time while
it is still opened by python. Close the file in python before
asking the compiler to read it.

See https://docs.python.org/3.7/library/tempfile.html#tempfile.NamedTemporaryFile

It is not needed in runtime at all.

This reverts commit 20d0e3b3.
