I'll file this as a feature request, though I'm slightly apprehensive of
adding this much magic on top of the language. I feel like ipython is
becoming more and more a 'new thing' on top of python.
But yes, I also see the convenience value here... I'm not really sure whether
to go for it (there is a runtime price to pay for the extra analysis, as well
as more complexity in the input analyzer, so thid doesn't come for free).
Note that you can already do this:
In : if 1:
....: print 'hi arnd'
....: for i in (1,2):
....: print i,
....: print 'bye'
1 2 bye
Just add an 'if 1:' at the first line, and paste away, even if the code is
indented multiple levels (the above was a chunk twice-indented in an emacs

They are, but ipython isn't into fixing anyone's moral compass :)
