would like this.

I finally liked pythons 'forced-indentation' thing, but 'self' is just

def deposit(amount)
    .balance = .balance + amount # a little thin this dot
    @balance = @balance + amount # why not similar to ruby?

    self = <do this and that> # self remains available

but this will have most possibly major implications (design,
compatibility etc.)

possibly the simplest way would be to agree on 's' (typing is very
fast, faster than SHIFT-2 for @)

def deposit(s, amount)
    s.balance = s.balance + amount

so, python 2.6 = introduces agreement on 's' ?

this will never happen, but everyone is of course free to use 's'
instead of 'self' immedeately.

There's no problem (except possibly the tiny annoyancy when reading
through libraries which use 'self').
