You know I've never thought braces where the problem in a language, and in 
python, not having them isn't a problem either.

The reason I dislike C is due to the amount of boiler plate and the low 
level of code, which requires managing memory, declaring prototypes and 
including headers.  All of which I think are much more troublesome and 
harder to get right than any amount of braces.

Both sides have advantages, but Python's design is meant to represent code 
in an easier to see and read way.  Representing blocks by indention is 
consistent with that.  (And so is outlines in written language.)

I could equally like a language where blocks are literal code objects that 
can be assigned to names.  In that case the block delimiters would be 
consistent with that language design and that would be perfectly fine to 
me.  The code would be representing what it does in an expected and useful way.

    block = {statement_1; statement_2; ...}

The cases in between seem a bit unclean to me however.  Where braces are 
used to define blocks that aren't exposed.  I think it's ok, but it also 
seems a bit unclean to me.  Adding more noise than necessary to the code. 
But I understand at some time, when a language was designed it may have 
been that it made parsing the language simpler.  (it does.)  Or it may have 
just been the language designers preference at that time.  <shrug>

But still, I think the whole braces are good/evil is over stated.  There 
are lots of more important things in languages to consider.

Cheers,
    Ron
