Hi all,
Thinking of a syntax for 'getattr' and 'setattr' dynamic access.
'obj.prop' has an easy access, but
att= 'prop'
getattr( obj, att )
is much clumsier, while no less useful, maybe more.
What are the changes, pros and cons, involved in something like:
obj:att for a dynamic access, and obj.att for static?
Snice readability is a factor, I'm open to other markings than ':'.
'$' and '?' are available, and I note that a~b, a:b, and, a!b for
identifiers 'a' and 'b' are unambiguous. |

maybe more? ok, you *are* utterly and completely unable to post
anything that makes any sense at all to anyone that uses Python.

Thanks for the reference. Well, check out the two alternatives, a~b
and a!b, which are easy on the eyes, and weren't proposed, but don't
allow expressions. (Turns out 'if a:b' is valid, so never mind that
one.) I also won't let you forget that $ and ? are unused so far
too. I see syntax was one of the complaints. |

More constructive contributions on both sides there. Good one. |
