The workaround now is to use the timeit command, which does send things to the preparser.

sage: timeit('[1..10]')
625 loops, best of 3: 220 µs per loop

Just because there is a workaround doesn't mean this should be closed. I reported this problem to Fernando Perez of Ipython and he "admitted" that it is a bug, and was working on fixing it at that last sage days. I'm re-opening this.

By the way, it's generally very bad for anybody but me or Michael Abshoff to close tickets on trac!

I only closed it after mabshoff gave his okay on IRC. I guess I should have posted the IRC log.
