You can talk about it on the generallist, as has been suggested to you before. But once an idea has beenlargely rejected, as this one has, this mailing list is no longer the rightplace for it.>> "burden to learn" - I hope you are not serious :)> No, this is serious.> You duplicate the syntax possibilities of one ot he> most basics syntactic elementsHow do you count duplicate? And what is the senseto speak about 'burden to learn' before the new syntax getapproved? If it will be the new syntax, thenyou will need to learn the new syntax only.The existing syntax will not be removed. It would break all python codeever written in the most fundamental way. That is never going to happen.You want throw iterables in it, do it:for e over Sequence :I see this probably could have some ambiguity problemsbut is it such an unsolvable problem?For integers write e.g. like this:for i over 0, N :orfor i over *N :What is the problem?So anyone learning python would need to know both syntaxes to be able towork with other peoples' code. But we would end up with two syntaxes thatdo exactly the same thing except with either an integer or two or threeintegers separated by commas, in which case they behave completelydifferently. That will be confusing even to experienced developers.-------------- next part --------------An HTML attachment was scrubbed...URL: <http://mail.python.org/pipermail/python-ideas/attachments/20170218/3f57914e/attachment.html>
