> SQLWindows had an outline-based code structure — not braces, not BEGIN/END, but an indented tree that was simultaneously the code and the IDE’s display. You wrote code by expanding and collapsing outline nodes. Classes were outline headings. Methods were sub-headings. Code lines were leaf nodes. The entire program was a hierarchical outline that the IDE rendered as a collapsible tree.

I am asking because I have never needed preserving the `$?` outside of an `if`, nor have I ever seen this in somebody else's scripts, and I'm curious.

There was one case where all transactions were implemented using nested `SAVEPOINT bla` so `BEGIN IMMEDIATE` could not be used without more hassle, so this ended all “I know I'm going to write” transactions to instantly update a single-row table so that their lock would not begin as DEFERRED and eventually switch to `IMMEDIATE`; this way almost all `SQLITE_BUSY` side-steppings disappeared. (timeout was set to 30 seconds but all read/write transactions were instrumented to have less than 5 seconds duration).

So this was a write to a column that did not have INTEGER affinity. If it was intended to be used as a boolean, then it should have INTEGER affinity. I know because I've tried hard to enter integer- and float-like strings as strings in INTEGER affinity columns, and I haven't managed to; I could only insert them as BLOBs, or prefix the string with say '\' and check/remove at the application level. (That was for an ontology-like database, where table EAttribute.eatvalue could have any type.)

> I agree, Python allows anyone to write bad code, but makes up for it by running the code slow enough that it can't do real damage.

In the same sentence you agree with the implied beauty of the syntax of Python and then go on sarcastically about the performance of CPython. Assumably you deliberately mixed language and implementation because you needed a soapbox, so hey, here's my comment to which you can reply and continue your rhetoric.

Now I can have side-by-side two editors plus a Structure or Project pane at the left in PyCharm while having 120 chars visible in both editors.

    import re, operator
    def count_words(filename):
        with open(filename, 'rb') as fp:
            data= memoryview(fp.read())
        word_counts= {}
        for match in re.finditer(br'\S+', data):
            word= data[match.start(): match.end()]
            try:
                word_counts[word]+= 1
            except KeyError:
                word_counts[word]= 1
        word_counts= sorted(word_counts.items(), key=operator.itemgetter(1), reverse=True)
        for word, count in word_counts:
            print(word.tobytes().decode(), count)

    $ cat
    ^Z[1] + Stopped                    cat
    $ kill %1

    IFS='   ''

    IFS='   ''

    echo hello >/tmp/"some_unique_prefix in tmp"
    cat /tmp/some_unique_prefix*
    fn="My CV.txt"
    echo "I'm alive" >/tmp/$fn
    cat /tmp/$fn

I remember using `cat -v` before learning that `xargs` exists… or maybe before `xargs` actually existed on systems I used :)
