I actually initially was going to suggest a `strict` flag get added, but I
figured that would be impractical. I was mostly concerned about classes that
mimic file objects, because (obviously) their read methods wouldn't include a
`strict` flag and you couldn't pass such objects to functions

Rather than a new function, maybe a flag?
read(n, strict=True)
(Not sure if a block flag would also be useful, but maybe)

What I said:
"Python, for good or ill, is an opinionated language regarding
indentation and statements."
And then Greg refuted something I never said:

The Python language isn't opinionated about line

ANYTHING can be done by composing concepts. We

While you can put the block on the same line as the colon using

The code I'm currently working on involves parsing binary data. If I ask for,
say, 4 bytes, it's because I actually need 4 bytes and if the file doesn't have
4 bytes for me, it's malformed. Because `f.read(4)` can silently return less
than 4 bytes and I don't want to have to explicitly double
15 matches
