Hmmm.. I think maybe if if don't ever access shape (or Shape) directly

... the function 'fn' does here. So they remain local bindings to
objects in the scope they were first referenced from even after the

And there would probably be ways to unlock objects. But maybe that's
not a problem as I think what you want to prevent is erroneous results
due to unintentional name changes or object changes.
I think both of these would have unexpected side effects in many cases,

Now that the syntax is settl

So ...
A if B else C + X * Y
Would evaluate as... ?
A if B else (C + X * Y)
and...
value = X * Y + A if B else C
would be ?
value = (X * Y + A) if B else C
or ?
value = X * Y + (A if B else C)
I think I'm going to make it a habit to put parentheses around these

That would be in place of..

a boon by others. If I'm right, there will be endless discussions over

apath.close()
etc...
With this you can iterate a file system as well as it's files. ;-)
(Add more or less methods as needed of course.)
apath = device(dev_obj).path(some_path_sting)
apath.open().write(data).close()
or if you like...
device(dev_obj).append(path_sting).open().write(data).close()
Just a few thoughts,

ct or modify the original?
p = path('C://somedir//somefile')
p+='.zip' what would this do?
p[-1]+='.zip' Or this?

I figured it was, but you offered a puzzle:
"Here
eeds some better logic to merge adjacent like groups. I
think the reverse sorting my be a side effect of the nesting that takes
place when the expressions are built.
Having the digits first might be an advantage as you can use a for loop
to add or multiply them until you get to a not digit.
Anyway, interesting stuff. ;-)
