no, the ability of having wrongly indented code throw syntax errors.
there are many workarounds for individual editors, but nothing to help
eliminate this error class altogether.

the many workarounds also lead to "more than one way to do it".  the
code I read can be using "#fi", "# end if", "# }", "pass" or nothing.
sure, I can write a tool to enforce a single coding standard for my
project, but external code will naturally not comply.  that's why I
think it would be good if Python decreed a single method of using both
belts and braces.

currently, I'm using the "nothing" style, and like it very much.  my
motivation is that a member of our development group religuously
litters his code with "#fi" and "#done".  rather than just tell him to
stop it, I thought I'd explore the avenue of a compromise, since I
myself would like to use braces in my code in some instances to
improve the visual cue in "deep" (4-5) indentation blocks.  (this can
happen even if the function fits on the screen.  splitting out the
core of it is in some cases awkward.)

I wouldn't say it's a frequent problem for me, it's happening me a
couple of times per year, and some of my colleagues report likewise.
but wasting perhaps a workday a year on such a silly issue is
annoying.

my hope is that my solution can be ignored by those who don't need it,
and used by those who like it.

no, it was a long, well thought-out article.  thank you.
