This has being thought, asked, and even agreed as nice thing before, however, it is blocked due
to ambiguity on the syntax for some corner cases - and, I may be wrong n that, it would not be possible
to do with the current parser (and Python is not shifting to a more complex parser for this feature alone).
So, anyway, the official recommendation for long `with` statements is to use the `\` line continuation character:
```
with \
open(fname1) as f1,\
open(fname2) as f2,\
open(fname3) as f3,\
open(fname4) as f4\
:
```
