It became customary among many users to abuse the quotation markup to indicate Mathematica output, like
Range[5]
{1, 2, 3, 4, 5}
I wonder whether it would be possible to create a MMA.SE specific markup, maybe something similar to the ==>
used by the copy/paste palette, that would create a dedicated Mathematica output code cell (which could have added features, as automatic Out[n] = ...
). The reason this doesn't exist is of course that no other site here has input and output mixed up that much. Seeing that it might be confusing right now for new users coming here from other SE areas, the matching idea of input/output grouping of Mathematica, and the customization possibilities, I thought this was a good idea to propose.
Out[n]= ...
for simple stuff and a(* Out[n]= ... *)
for more complicated stuff.==>
for each piece of output. I agree that a dedicated format with less wasted space, resembling actual Mathematica-output, would be better, but until it is implemented, I rather stay with the quotes.
