What do you propose we do about the commas in loops? Breaking them
would be a pretty big change to the C folks.
With the naked comma tuple, how do you pass them to a

There are ways -- elegant ways, I believe -- to make it work.

Looking at it quickly, the big difference seems to be you leave the tuple
word off, and use them in more places.

Hm. Then I believe you haven't read the whole thing. (That's ok, it does go

It's trivial to allow a comma-separated list of expressions in the for
loop header. If Pythonic tuple syntax were used (i.e.

Why would you ever want to do that when you have:
a = 2;
b = 3;
I see people ask why would you ever

Yeah, I just briefly skimmed it. I'll have to go back to it for a full read
when I have a little more time.

This actually doesn't /quite/ work, since the tuple returned by tuple() has
unnamed fields, which is a different type than the one with named fields.
Gah.

Remember delegate literals? They were just a few more tokens, but it
wasn't until the shorthand syntax was introduced that everyone started
using them. I mean, how hard is it to type the e

Interestingly, I've been looking at tuples almost entirely as "anonymous
structs", if you will. Perhaps this is another bias preventing me from seeing
